• Rainfall infiltration simulation on embankment containing soluble material

  Katsuyuki Kawai, Kaito Arinishi, Satsuki Kataoka, Koji Nakashima

  Recently, mixtures of low-quality soil together with solidification materials, such as cement or steel slag, have been used for earthmoving construction. Solidification materials can improve consistency, shear strength, stiffness, and other parameters of low-quality soil by generating bonding forces between soil particles and changing grain size gradation. However, these solidification materials also contain chemical agents. In this study, simulations of rainfall infiltration into embankment constructed with the soil-solidification material mixture are conducted using the soil/water/air/soluble material coupled finite element analysis code, DACSAR-MP_ad. This analysis code can express not only deformation and seepage for an unsaturated earth structure but can also concurrently model the dispersing behaviour of soluble material. Herein, permeability and rainfall intensity conditions are provided and their effects investigated. Consequently, this study succeeds in expressing different distributions of soluble materials within embankment under different rainfall conditions.

• Full-scale Experiment on New Seismic Reinforcement for Road Embankment by Using Flexible Container Bag - Verification for Early Restoration and Mid and Long-term Maintenance of Roads After an Earthquake Disaster -

  日本全国に広がる道路盛土の多くは，抜本的に，維持管理を要することはよく知られている．日本国内には耐震性の低い道路盛土が多数存在し，盛土材料の質が低く，不十分な締固めにより施工されていることが大きな理由の1つとなっている．これらの問題を解決するため，道路管理者にとっての緊急課題として，効率的かつ経済的な耐震補強工法の開発が必要であると考えた．そこで，本研究において，現地の盛土材を再利用することを目的に，大型土のうを用いた道路盛土の耐震補強方法を提案した．本研究資料では，既設盛土の法先部に複数設置された土のう構造体の補強効果を検証するため，Ｅ－ディフェンスにおいて実大道路盛土の震動台実験を実施し，その結果を中心に報告している．一連の実験結果から，定性的ではあるが，土のう構造体の補強効果による盛土の耐震性向上の可能性が確認された．It is well known that many of the existing road embankments spreading across Japan require drastic maintenance, because their earthquake resistance is considerably questionable due to the poor quality of the embankment materials used and insufficient compaction. In order to solve these problems, it is important to develop efficient and high cost-performance methods as an urgent task for engineers in charge of road management. Therefore, the authors proposed a seismic reinforcement method for road embankments by using flexible container bag that can reuse local embankment materials. In this study, a series of shake table tests on a full-scale road embankment was conducted at E-Defense in order to verify the reinforcement effects of the flexible container bag structures installed at the toe of the embankment. Based on the results obtained from the shake table tests, it was qualitatively confirmed that the flexible container bag structures can improve seismic resistance of the whole embankment.

• Evaluating aseismicity of an embankment constructed with the mixture of steel slag and fine grained soil

  K. Jeong, J. Baek, S. Kataoka, S. Shibuya

  In this paper, the physical and mechanical properties of a fine grained soil mixed with two types of steel slag were thoroughly examined in the laboratory. The behavior of a full-scale test embankment of the steel-slag-mixed soil when subjected to traffic loading was also observed over the period of nearly two years. Moreover, numerical analysis was carried out in order to evaluate aseismicity of the embankment based on the results of in-situ and laboratory tests. It was manifested that the performance of the steel-slag-mixed embankment was satisfactory by showing no harmful deformation. The result of numerical analysis clearly showed that the factor of safety of the steel-slag-mixed embankment was much higher than that of a comparative embankment without the steel-slag. In addition, the amplification of horizontal response acceleration decreased noticeably for the steel-slag-mixed embankment, suggesting strongly that the steel slag may improve greatly aseisimicity of fine graded soil in used for fill material.

• Seismic behavior and numerical simulation of earth-fill dam with geosynthetic clay liner in shaking table test

  Kyungbeom Jeong, Satoru Shibuya, Satsuki Kataoka, Jemin Baek, Toshinori Kawabata, Yutaka Sawada, Hiroshi Nakazawa

  In this paper, shaking table tests by using a small-scale as well as a full-scale earth-fill dams with geosynthetic clay liner were carried out in order to examine aseismicity of these earth-fill dams. Moreover, the behavior of these fully instrumented earth-fill dams subjected to seismic loading was simulated by numerical analysis. First, in the small-scale shaking table test, there observed no failure along the geosynthetic clay liner when the earth-fill dam was subjected to seismic motion. When the stability of the model dam was simulated by pseudo-static limit equilibrium analysis, and also the seismic response was simulated by FEM seismic analysis, it was successfully confirmed that the behavior of the model earth-fill dam was unaffected by the existence of the geosynthetic clay liner. Second, comparative shaking table tests by using a full-scale earth-fill dam with sloping core zone and the other with geosynthetic clay liner were carried out. The acceleration response as well as the deformation behavior was similar between these two models, both having 3m high. It should be mentioned that the acceleration response increased gradually towards the dam top and the deformation after shaking was relatively large near the foot of the slope. These observations were, to a great extent, successfully simulated by the numerical analysis.

• Seismic behavior and numerical simulation of a small-sized earth-fill with bentonite sheet observed in shaking table test

  Jeong Kyung-Beom, Shibuya Satoru, Kataoka Satsuki, Baek Je-Min, Kawabata Toshinori, Sawada Yutaka

  Recently, a bentonite sheet is often employed in deteriorated earth-fill dams for preventing water leakage. However, it is concerned that a slipping type of failure may occur at the boundary between the bentonite sheet and the fill material in the event of seismic attack. In this paper, seismic behavior of a small-sized earth fill model inside which a bentonite sheet was mantled was examined in shaking table test, and it was simulated by numerical analysis. It is manifested in the shaking table test that a shallow slip surface developed in the fill above the bentonite sheet, and no harmful deformation was observed along the bentonite sheet when subjected to seismic motion, noting also that the shallow failure was successfully simulated by pseudo static limit equilibrium analysis. In addition, it was confirmed that the seismic response of the model earth-fill was unaffected by the existence of bentonite sheet as examined by FEM seismic numerical simulations.

• Estimation of consolidation properties and the settlement of Pleistocene clay layer at Kobe Port Area

  E. K. Ha, S. Kataoka, S. Nonami, T. N. Lohani, S. Shibuya

  In this study, a series of the constant rate of strain (CRS) test was performed by using undisturbed test samples retrieved from the Pleistocene clay layer at Kobe Port area. The OCR of the marine clay layer was then obtained from the stress-strain-strain rate dependency relation. On estimating the settlement amount of the Pleistocene clay layer at Kobe port by using the OCR value of 1.2 and 1.25 obtained from OCR-strain rate plot, it was found that estimated settlement matched quite well with the measured value of the site. The study shows an important aspect of OCR estimation of in-situ soils from the laboratory CRS test on undisturbed soil specimens in order to calculate the in-situ consolidation settlement with accuracy.

• Effect of grain-size distribution on cyclic strength of granular soils

  J. H. Lee, S. Shibuya, T. N. Lohani, T. Wakamoto, S. Kataoka

  Earthquakes are quite frequent in Japan. Liquefaction cases are often reported in the grounds which were not thought of liquefiable previously because they included larger gravel fraction or fine fraction. In this study, effect of soil gradation characteristics has examined in detail considering their critical role. The cyclic strength properties of the fill materials consisting of various gradation were investigated by using five soils with D-max = 2 mm and two, D-max = 19 mm from different sites in Hyogo prefecture, Japan. By preparing the test samples at the degree of compaction of 85%, 90% and 95%, based on the recommended values for various embankment types in the field, undrained cyclic triaxial tests were conducted in order to evaluate the liquefaction resistance of each soil type. Results show that increase of cyclic strength against the dry density was largely affected by the fines content (F-c) and average particle size (D-50) among others, of the tested soils.

• Geotechnical engineering characteristics of 'Polishing Sand' in Handa area, Japan

  Takahisa Nishioka, Satoru Shibuya, Satsuki Kataoka, Tomoya Kitano, Nidhi Lohani

  Engineering properties of local soil called 'Polishing sand' distributed over the southern district of Tsu-shi in Mie Prefecture was examined by performing laboratory tests. Polishing sand at natural state is found as a sedimentary soft rock with average strength parameters, qu = 0.2 to 3.4MPa, ccu = 100 to 200 kPa,φcu 40 ∼ 50 degrees and it transforms into a homogeneous grayish-white sand when exposed to the surface by excavation. Looking on the average strength parameters of the disintegrated sand, ccu = 10kPa, φcu = 36°, a drop in qu to almost 1/10 or smaller level than that at natural state is observed. The difference in properties of these two states of the same material are considered to be due to cementation and crystallization effects between soil particles. When in a natural state, the anisotropy evaluated by triaxial tests with bender elements shows Ghh/Gvh = 1.4∼1.5 at mean effective confining pressure, p'= 0∼100kPa and Ghh/Gvh 1.0 at 100 < p' 400kPa. This shows an anisotropic behavior at deposition because of cementation and its destructuration afterwards at higher confining pressure. Additionally, the relation between qu and G has been elaborated by comparing it with cement-treated soil and by discussing physical and chemical aspects of cementation.

  In this study, to clarify the distribution of gas-hydrate and its formative environment of seabed methane, and to evaluate the potential as resource of gas-hydrate, the geologic surveys were conducted by NT13-20 and OS263 cruises covering a wide area of Abashiri and Shari Submarine Canyons in the Okhotsk Sea. The conducted investigations are the seismic geologic survey, the bathymetry and the gas-flare observation by an echo sounder, and core sampling of sea-bottom sediments. Moreover, to examine the soil properties of sea bottom sediments, some kinds of shipboard tests such as handy vane shear and cone penetration tests, and physical properties tests such as water content and grain size distribution tests, were performed for the samples.

• Evaluating deformation and liquefaction properties of sandy ground from in-situ and laboratory tests

  Obtaining good samples from loose sand layers within bay areas are necessary to evaluate their deformation and liquefaction properties. Until now, high-quality sampling in the loose sandy ground are achieved by applying an expensive in-situ freezing technique. In order to find an alternative and cost-effective sampling method applicable to these loose alluvial deposits, sand samples were collected in this study from Kobe Bay area by using two different types of sampler and were comparatively examined by evaluating their physical properties, deformation characteristics and liquefaction strength. A close match of relative density, deformation properties and that of liquefaction strength properties to that of the field was shown by the samples collected by GS sampler than the Triple-tube types. This suggests a possibility of using a relatively less expensive GS sampler to collect high-quality samples from a loose sandy ground that is now primarily being applied for waste collection.

• The soil properties of lake-bottom sediments in the lake baikal gas hydrate province

  Satsuki Kataoka, Satoshi Yamashita, Takayuki Kawaguchi, Teruyuki Suzuki

  The purpose of this study is to understand the soil properties of grounds which contain shallow type gas hydrates. For this purpose, the surveys were conducted in Lake Baikal, Russia from 2005 to 2007, where shallow gas hydrates existed. For the lake-bottom sediments, physical and mechanical properties were tested (on-board and laboratory tests). The tested samples were retrieved from the mud volcano ground which contains the shallow gas hydrates, and reference ground at the same area. From these results, it was found that the gas hydrates distribute in large amounts in the lake-bottom sediments of Lake Baikal, and that form of the gas hydrates are varied. In addition, the reference samples in Lake Baikal have no marked differences in the soil properties of the sediments obtained from other sea-bottom grounds. On the other hands, the strengths of the mud volcano samples were lower than those of the reference samples. It would seem that these results are due to the effect of the disturbance of sedimentary layers by upwelling of gas and water from underground and the pressure release during the sampling.

• Approximation of Gas Volume in a Seafloor Sediment using Time Domain Reflectometry from gas hydrate research in the eastern margin of the Japan Sea (MD179)

  AOKI Shinsuke, OCHIAI Hiroyuki, MATSUMOTO Ryo, KATAOKA Satsuki, NOBORIO Kosuke

  As concentration of carbon dioxide in the atmosphere due to consuming fossil fuels has increased, global warming is accelerated in last decades. In addition, increases in consuming fossil fuels have led to their depletion in recent years. One of the practical measures to those two challenges is the conversion of energy resources to natural gas having less environmental impact. Gas hydrates trapping natural gas have been discovered in the sea around Japan. They are expected to serve as a new non-conventional natural gas resource. To understand the mechanism of gas hydrate accumulation, the amount of free gas in sediments should be known. However, without affecting other properties, its non-destructive measurement is difficult. Therefore, we examined a new technique for measuring the amount of free gas using Time Domain Reflectometry (TDR). TDR has been popular to measure moisture content of soil. In this study, we estimated a gas ratio in the sea-bottom sediment obtained from the Eastern Margin of Japan Sea using TDR. We found that the gas phase exist up to about 7%.

• Physical and thermal properties of mud-dominant sediment from the Joetsu Basin in the eastern margin of the Japan Sea

  Physical properties (bulk density and porosity) and thermal properties (thermal conductivity, heat capacity, specific heat, and thermal diffusivity) of sediment are crucial parameters for basin modeling. We measured these physical and thermal properties for mud-dominant sediment recovered from the Joetsu Basin, in the eastern margin of the Japan Sea. To determine thermal conductivity, heat capacity, and thermal diffusivity, the dual-needle probe method was applied. Grain density and grain thermal properties for the mud-dominant sediment were estimated from the measured physical and thermal properties by applying existing models of physical and thermal properties of sediment. We suggest that the grain density, grain thermal conductivity, and grain thermal diffusivity depend on the sediment mineral composition. Conversely, the grain heat capacity and grain specific heat showed hardly any dependency on the mineral composition. We propose empirical formulae for the relationships between: thermal diffusivity and thermal conductivity, and heat capacity and thermal conductivity for the sediment in the Joetsu Basin. These relationships are different from those for mud-dominant sediment in the eastern flank of the Juan de Fuca Ridge presented in previous work, suggesting a difference in mineral composition, probably mainly in the amount of quartz, between the sediments in that area and the Joetsu Basin. Similar studies in several areas of sediments with various mineral compositions would enhance knowledge of the influence of mineral composition.

• COMPARING SRTEGTH CHARACTERISTICS OF TWO TYPES OF GEOTEXTILE EXAMINED BY IN-SITU PULLOUT TEST

  NONAMI Satoshi, SHIBUYA Satoru, KATAOKA Satsuki

  A comparison of strength characteristics of two types of geotextile subjected to pullout force was made by means of in-situ pullout test. It was well demonstrated that the pullout strength property consisted of two components; i.e., the frictional resistance between soil and geotextile, together with in-soil interlocking effect of geotextile. Moreover, an integral type at the lattice nodal point exhibited larger interlocking effect than an bonded type. Based on the test results, it is strongly suggested to employ an integral type of geotextile in well-compacted fill material so that the pullout deformation of geotextile may well be restrained due to the interlocking effect.

  In this study, to evaluate the effect of the vaporization of dissolved gas in the pore water on the strength properties of sea-bottom shallow sediments obtained from deep seabed, core samplings were conducted in offshore Sakhalin Island, Sea of Okhotsk shallow gas hydrate province. Some kinds of on-board tests such as vane shear and cone penetration tests and physical properties tests such as water content, grain size distribution, specific gravity, plasticity tests were performed for the samples. These test results were compared to the concentration of dissolved gas in the pore water of the samples.

• Study on stability evaluation of steel slag as road embankment material focused on the improvement effect of low quality soil

  Satsuki Kataoka, Satoru Shibuya, Katsuyuki Kawai, Ryo Matsuo

  © 2019 Author(s). In this study, based on field measurements conducted during the period from the start of embankment launch to dismantling, based on the results of the indoor tests on the sampled samples, the deformation and strength characteristics of the embankment receiving the traffic load and rainfall Etc., the performance of the steel slag mixed soil as an embankment material was evaluated by paying attention to the hydraulic characteristics of the embankment. As a result, by mixing and stirring the steelmaking slag and the earth at an appropriate ratio and properly compacting, it is possible to withstand deformation even under traffic load, and it is possible to suppress leaching of high alkaline water from the embankment by rainfall to some extent It could be confirmed. Therefore, it was found that there was no practical problem concerning the concern factor when slag was used as the embankment material.
