  • Low-cost monitoring and visualization of changes in magnetic field caused by soil erosion behind a concrete wall

    J. Oshima, S. Akutagawa

    ©2019 Japanese Society for Rock Mechanics, This paper introduces a new method for detecting void formation caused primarily by water-induced soil erosion by using a magnet, a compass and a plastic optic fiber sensor. The proposed method starts by putting a magnet at an arbitrary point in a soil mass behind a concrete wall whose thickness would be in the range of 20cm to 35cm. A compass is placed across the concrete wall such that its needle initially points in an arbitrary direction which does not coincide with the Earth’s north-south direction. Then, water is supplied onto the soil mass such that portion of the soil mass is eroded and eventually the magnet is forced to move, changing the magnetic field around it. The compass then detects this change in the magnetic field and its needle changes its direction. This needle movement, caused by the soil erosion occurring behind the concrete wall, can be seen by naked eyes or be detected by the plastic optic fiber sensor with ease and accuracy. The original concept in this method is that the important information to be captured in advance, can be remotely obtained across thick concrete walls with the help of magnetic field.

    © 2019 Taylor & Francis Group, London. A trial investigation was undertaken to evaluate the feasibility of applying a uniquely designed optic fiber sensor for detection of water leakage in a metro tunnel in Tokyo. To conduct effective maintenance works for underground infrastructures constructed several decades ago, it is essential to perform a thorough inspection for damage states of concrete structures that may be induced by water leakage from cracks over time. The results of the investigation indicated that the proposed sensor is capable of detecting water leakage both in laboratory and field, suggesting that the method would be readily applicable for practical use in maintenance works for aged concrete structures.

  • Application of a new plastic optic fiber sensor for detection of water and its phase change in geo-materials

    Y. Tanaka, S. Akutagawa

    ©2019 Japanese Society for Rock Mechanics, In this research, we developed an optical fiber sensor that can observe changes in the refractive index of light. This sensor is called an RR sensor because it uses the reflection and refraction phenomena of light. The advantage of the RR sensor is that it can obtain local information by using a method different from the conventional fiber optic sensor. In particular, the RR sensor is excellent in detecting presence of water. This paper presents an example of monitoring the arrival of infiltration water inside the concrete specimen and the freezing and thawing of water in the sand.

    A monitoring system, called the optic sediment sensor (OSS), for study of the detailed processes of bathymetric changes in the surf zone has been developed. The OSS system consists of an array of fiber gap sensors (FGSs), a support structure (steel pipes), an electronics unit that transmits and receives light through fiber-optic cables, and a data acquisition system. The FGSs are mounted in a 2-m long vertical steel pipe; the sensor spacing is 10 cm. Steel pipes containing FGSs were embedded in the seafloor at two places at water depths of 4-5m beneath a pier at the Hazaki Oceanographical Research Station (HORS) (Port and Airport Research Institute) on the Sudahama Coast, facing the Pacific Ocean, Japan. The electronics unit and the data acquisition system were installed in an observation room on the pier. The OSS systems successfully recorded well-defined and consecutive bathymetric changes caused by storm waves (maximum significant wave-height = 3m); e.g. reversal of seabed erosion and deposition within a day could be recognized. If the OSS system could be installed in many more locations along the pier, the consecutive process of the formation, migration, and deformation of the whole of the longshore bar may be clarified.

  • The development of low cost Mechanical OSV (On Site Visualization) and its application on Bai Chay Bridge approach road in Vietnam

    C. Izumi, S. Akutagawa, H. Zhang, K. Tsujimura

    OSV (On Site Visualization) in which the measured information is shared visually on a real time basis at site was introduced by Akutagawa in 2006 and it has been applied at various construction sites effectively. The basic function of OSV device is to show the change of deformation, pressure, inclination, etc of the structure as well as the ground by the colored light, namely blue, yellow and red through Light Emitting Converter (LEC) and LED lights electrically. Through those experiences, we recognize one of the big issues is the cost of OSV devices to utilize them at large area for more effective OSV operation. The simple monitoring devices without electricity are sufficient to monitor fundamental ground movement and low cost mechanical OSV devices are introduced at Bai Chay approach road as first trial of mechanical OSV monitoring.

  • Monitoring and data-visualization of displacement for NATM tunnel constructions

    S. Akutagawa, H. Zhang, M. Terashima, K. Tsujimura

    Monitoring work plays an important role for safety management during tunnel construction. The observation objects mainly consist of ground deformation, convergence displacement, axial force of rock bolts and so on. It is still insufficient to meet the practical monitoring needs due to the dynamic construction procedure, the deformation characteristics of rock as well as the cost. In this paper, the new concept of "On Site Visualization" is illustrated briefly for construction management. Then, based on this concept, some simple methods are proposed to measure the displacement and visualize the data on real-time during tunnel constructions. By using these methods, the displacement, such as the ground deformation ahead of tunnel face and the convergence displacement, can be monitored and visualized in a mechanical way. In addition, experimental examples for construction practices are introduced and analyzed. Finally, the possibility of using these methods for tunnel monitoring and visualization is discussed.

    Despite of the advancement of monitoring devices at construction sites and the rapid progress of data management and IT, accidents in construction are still threatening not only site workers but also the public. It is difficult to cover all the dangerous areas on a construction site with expensive devices. To overcome these problems, a new monitoring method, called On Site Visualization (OSV, for short), has been developed. Unlike a conventional method of data acquisition, the use of light emitting sensors to execute monitoring by OSV enables real-time data processing and visualization on-site, so that the state of deformation, strain, inclination and etc. of concern is grasped with no delay in time and is shown visually to anyone nearby. Rational use of the new scheme based on the OSV offers a new stage whereby visually shared real-time information about the structures of concern could lead to a new paradigm of field measurement and a safer working environment. This paper describes the application example of the OSV monitoring system in the open cut excavation site of Delhi Metro in New Delhi, India. In the evaluation of the project, the role and effectiveness of OSV as a part of safety management were confirmed through a questionnaire survey given to the workers and public citizens.

  • On-site visualization monitoring for long span bridge on Delhi Metro Project

    Chitoshi Izumi, Shinichi Akutagawa, Ch. Ravi Sekhar, Rajan Kataria, Reiko Abe, Hirofumi Haga

    A new monitoring scheme, based on the concept of on-site visualization (OSV), was successfully applied for monitoring safety conditions during construction of a long span cantilever bridge in Delhi Metro Phase-II project in 2010. The bridge construction with challenging features included a 100 m long span over the Northern Railways tracks passing below, the balanced cantilever construction methodology with a see-saw condition of the pin-connected girder during segment casting processes and a horizontal curvature of the girder with 300 m radius. The light-emitting sensors with dual functions, namely sensing and simultaneous visual output of measured results, were employed in this project and played crucial roles to capture unique behaviours of the bridge under construction and to ensure safety throughout the project.

  • Measurement and real-time visual presentation of ground deformation ahead of mountain tunneling face using optical fibers

    S. Akutagawa, H. Zhang, M. Terashima, K. Tsujimura

    There is an urgent need of newstrategy for the monitoring of groundmovement ahead of mountain tunnel face to improve the safety management. A new sensor is under development for the monitoring based on the concept of "On Site Visualization". This method is different from the conventional field measurement techniques in that deformation is measured on site and visualized by different colors of light in real-time. Since this method makes use of optical fibers as the light propagation medium, it could keep on visualizing the displacement of measuring points even if its front part is cut as needed during excavation. The paper presents some laboratory experiments to demonstrate the applicability of this scheme. By doing this, it is found possible to monitor the ground deformation by the proposed sensor. Finally, some work in future is discussed briefly.

    S. Akutagawa, Y. Minami, H. Yamachi, T. Haba, T. Hiroshima, T. Nozawa

    Light Emitting Deformation Sensor is applied for ground anchors and rock bolts. By adding additional elements to original ground anchors and rock bolts, the new types are capable of showing current axial force in them by color of LED that changes according to magnitude of the force. Real time measurement of these forces and simultaneous presentation on site, leads to safer working environment since any symptom for larger deformation can be grasped with no time delay. In addition, simple axial force presentation by changing color of LED might help upgrade the management efficiency of those rock support measures and grasp axial force distribution in underground structures as a whole.

  • Light emitting sensors as new visual tool for rock structure monitoring

    S. Akutagawa, A. Kusui, M. Nomura

    Several application examples are shown in which Light Emitting Deformation Sensors are used for deformation monitoring of infrastructures (slopes, tunnels, etc) and other purposes. Unlike conventional method of data acquisition, the use of this new device enables real-time data processing and visualization on-site, so that the state of deformation for a rock structure in concern is grasped with no delay in time and is shown visually to anyone nearby. Rationally designed use of this sensor could minimize risks not only during construction of infrastructures but also during their service time.

    In NATM tunnel constructions passing through unconsolidated soil and shallow depths, it is inevitable that ground displacement will occur around tunnels, which may significantly affect nearby structures. Experimental and numerical analysis approaches have been undertaken to understand deformation behaviors during tunneling. This paper consists of two phases. In the first phase, a numerical model that can account for reduction of shear stiffness and frictional strength parameters simultaneously was proposed to investigate the effects of key parameters on the deformation mechanisms on key parameters, e.g. nonlinear parameters, horizontal stress ratio, and shotcrete thickness. The second phase was performed to compare model test results with those of numerical modeling, for validating the proposed strain-softening analysis method. © 2008 The Society of Materials Science, Japan.

    Artificial Neural Network is used as a key technique for back analysis in a nonlinear tunneling problem. Database is created by performing series of nonlinear finite element analysis while varying parameter values within reasonable ranges determined from experience. Neural networks created from this database are found to be able to identify parameters concerned with both linear and nonlinear deformation behaviors of shallow tunnel. The exercises conducted here show that the proposed method has reasonable stability in all aspect of data preparation and computation and could be a new engineering tool for modern tunnel engineers.

    Back analysis of a ground deformational behavior involving nonlinear behavior is discussed. It is of primary importance to make reliable prediction of deformational behavior for shallow tunnels in soft ground. However, predictions made often prove to be incorrect due to complexity of constitutive law and other relevant factors. Back analysis therefore becomes more important, for it may be used to interpret measured displacement to derive non-linear material characteristics. The paper shows some example in which a deformational mechanism is studied in the light of inhomogeneous distribution of Young's module, from which a logic is derived to identify two different types of nonlinear constitutive relationships.

    A large scale rock slope failure, with an estimated collapse volume of 2 700 000m 3, occurred at a site where the deformational behavior had been monitored over several years. The characteristics of the behavior were in that the deformation was recorded not only during excavation of the slope, but also between excavations. This paper presents a summary of an investigation on the deformational mechanism both during and between excavations. In particular, a finite element procedure used herein has introduced a new method of modeling deformation between excavations as that associated with a reduction of material strength parameters. The results of this investigation suggest that a sign of a large scale collapse might have been seen in a relatively early stage of the slope excavation procedure.

  • On the systematic identification of deformational mechanism of shallow NATM tunnels during excavation

    JH Lee, N Doba, Y Yokota, S Akutagawa, T Kitagawa, N Nakayama

    Deformational behavior around a shallow NATM tunnel is often characterized by formation of shear bands developing from tunnel shoulder reaching sometimes, to the ground surface during excavation. This paper tries to identify deformational behavior of a shallow NATM tunnel in soft ground using a strain softening model. The analysis is carried out by comparing the calculated deformation with obtained data from field measurement. The results of a series of computation are discussed and an attempt is made to identify both the design input parameters and the mechanism governing the development of the surface settlement profile.

  • Incorporation of elastic strain distribution for improvement of back analysis in nonlinear problems

    S Akutagawa, A Hasegawa, JH Lee

    A useful technique for improvement of back analysis for nonlinear problems is introduced. A series of algorithms developed for linear and nonlinear problems for underground excavation work quite well to certain satisfaction level. However, as long as a set of nonlinear problems are concerned, the quality of back analysis obtained by existing methods is not necessarily good enough. The objective of the work presented in this paper is to improve the quality of back analysis for nonlinear problems.

    S Akutagawa, M Ota, K Yasuhara, K Matsuoka, T Oda

    A magnetic anisotropy sensor is used for nondestructive measurement of stress on surfaces of a ferromagnetic material, such as steel. The sensor is built on the principle of the magneto-strictive effect in which changes in magnetic permeability due to deformation of a ferromagnetic material is measured in a nondestructive manner, which then can be translated into the absolute values of stresses existing on the surface of the material. Proper treatment of boundary conditions allows determination of stress tensor completely on surfaces of H-beam flanges, for example. This technique was applied to measure stresses of H-beams, used as tunnel support structures, to confirm expected measurement accuracy. The results show that this method could be one of the promising technologies for non-destructive stress measurement for safe construction and probably maintenance of rock structures.

    This paper tries to find how the difference of strain softening characteristics influences the deformation mechanism of ground around shallow non-supported tunnel by numerical analysis. The results show that it is possible to evaluate the onset and progress of deformation mode to collapse by a common criterion. This implies even if the details of strain softening characteristics are not known completely, the outline of deformation mechanism can be defined with ease, which provides useful information for field engineers.

    The paper discusses the results of numerical investigation on the displacement confinement effect of support structures of a NATM tunnel. The main focus of the investigation is on the use of a finite element procedure considering strain softening behavior. Some numerical examples are conducted in which relation between deformation involving highly nonlinear nature and tunnel support. A simple method is suggested to illustrate the effect of tunnel support in reducing ground displacement.

    A magnetic anisotropy sensor is used for nondestructive measurement of stress on surfaces of a ferromagnetic material, such as steel. The sensor is built on the principle of the magneto-strictive effect in which changes in magnetic permeability due to deformation of a ferromagnetic material. And it can show the absolute values of stresses existing on the surface of the material. Proper treatment of boundary conditions allows determination of stress tensor completely on surface of H-beam flanges, for example. And then we try to use the sensor first to measure stresses on surfaces of four straight H-beams having the length of 2m which is used as structural elements in tunnel support systems.

We try to introduce this method to tunnel support system. And firstly we used the sensor to measure stresses on surfaces of four straight H-beams having the length of 2m. This time we bent three of them in a factory to make curved H-beams for tunnel support with approximate radius of 6m, for which the second measurement was conducted

    This paper proposes an innovative back analysis method to model out inhomogeneous behaviors, which is suitable for cavern excavation in rock masses with a loosened or fractured zone. This method allows us to estimate the extent and characteristics of inhomogeneous zones with iterations, defining the reduction factor of elastic modules by strain outputs and following the back analysis formulation to take initial stress parameters as well as non elastic strains as unknowns with minimum norm solution. It is applied to the numerical experiments and also the actual cavern construction problem and the results suggest that more reasonable strain distributions with proper reduction factors can be appropriately estimated in a reasonable calculation time.
