    The water retention tests in this study were conducted using wettable and water repellent soils to investigate its water retention characteristics. For this, a newly established water retention testing system which uses continuous pressurization method was utilized, and the water repellent sand was artificially prepared by the silanization process. As a result, it was confirmed that the testing time for the drying and wetting processes in the soil water characteristic curve was remarkably shortened. The air entry value of the water repellent soil is similar to that of the wettable soil, while the water entry value and water infiltration value of the water repellent soil are smaller than the wettable soil. Even with a limited data, this indicates that the effect of the repellent state on soils has a larger hysteretic behavior than the wettable state on soils due to material characteristics.

    An embankment material is generally comprised of the gravel, sand, silt and clay. In particular, the fine grain content (Fc, under sieve #200) affects the mechanical characteristics of an embankment under unsaturated state such as the shear strength and the infiltration at a rainfall. Thus, a series of the constant water content compression tests in this study is performed on the Fc from 10% to 50% using a decomposed granite soil of the embankment. The shear behavior according to the Fc are examined with the degree of saturation. The increase of the shear strength, that is, an apparent cohesion due to the suction on the Fc is also examined through the comparison with the theoretical result based on the Suction stress - SWRC Method (SSM). It could be understood that the effect on the shear strength over Fc= 25% is maximized, and the soil sample over Fc= 25% would have a decided advantage as an embankment material.

    The slope failure so far has been occurred due to the heavy rainfall, and induced losses of a human life and properties produces. In order to prevent these damages, the measurement and the evaluation for the strength characteristics of the ground such as the shear strength and the angle of internal friction should be required. The direct shear box test (DST) for this has been generally used. Kim et al. (2012) reported that the result in the DST could be varied according to the difference of the opening size between the shear boxes, and suggested the Threshold-Line (TL) as a standard for the opening size. Thus, the suggestion of the opening size by Kim et al. (2012) in this study was discussed through the distinct element method (DEM) simulation. As a result, the shear behaviors obtained by the DEM simulation are similar to their experimental results. Thus, it is expected that the TL can be a standard for the opening size between the shear boxes.

    This paper examined the application of suction stress on the results of the direct shear test under constant volume condition for unsaturated soil as a subsequent study carried previously out under a constant pressure condition. In particular, the direct shear apparatus used was a modified type for unsaturated soil, and the opening between the upper and the lower shear boxes was applied with Teflon sheets. The suction stresses of each test were derived by means of the Suction stress-SWRC Method (SSM). As a result, it was found that the stress paths for unsaturated soil agreed well with the maximum volumetric compression point (M.C.P.) line, which was obtained under saturation and constant pressure conditions, through applying the suction stress in the (σnet,τ) plane. These results therefore showed that the suction stress derived from the application of the SSM can be considered to explain the mechanical behavior in saturated and unsaturated soils regardless of the two test conditions in the direct shear test. © 2013 Elsevier B.V.

  • Characterization of geomechanical and hydraulic properties of non-wettable sands

    D. Kim, H. -J Yang, T. S. Yun, B. Kim, S. Kato, S. -W Park

    Wildfire, diagenesis, and organic contamination often induce the non-wettability in soils which in turn dominate physico-mechanical behaviours and control the contact angle and capillary pressure. This study presents the characterization of hydraulic and geomechanical properties of non-wettable sands using artificially synthesized hydrophobic sands. The critical hydrostatic pressure that initiates the fluid intrusion into dry hydrophobic sands is measured to estimate permeation boundary. Hydraulic conductivity values of both hydrophilic and hydrophobic sands under fully saturated condition are examined to evaluate the drag force effect. For geomechanical study, a series of constant water content compression tests are performed to assess the mechanical behavior on a reconstituted specimen of unsaturated non-wettable sands. The stress-strain relationships according to the degree of saturation under confining pressure condition are observed so as to derive the suction stresses. Results highlight that the surface modification at nano-scale determine the spatial configuration of water phase in pore space and its impact on fluid flow and strength with varying degree of saturation prevails.

    This paper examines the effect of the opening between the shear boxes on the shear behavior in the direct shear box test (H=20 mmxD=60 mm) under a constant vertical stress using seven types of granular material. It is observed that the magnitude of shear strength and dilatancy decreases due to the outflow of sample with an increase in the opening. The two notions of the Threshold Point (TP) as the limit opening size and the Threshold Line (TL) offering the guideline of opening size is defined according to the mean particle size of soil samples. However, similar shear behaviors were observed regardless of the opening size because there was no outflow of sample through applying the Teflon sheet in the direct shear box tests for Toyoura sand. Finally, the shear mode on the circular specimen applying the Teflon sheet is also examined in comparison with the results from other tests.

    Unconfined compression tests are performed in this study to evaluate the effect of matric suction on the strength and the deformation characteristics of dynamically and statically compacted silt soils. In order to estimate the suction stress, the change in suction and the volume change of the soil samples are measured, and the relationship between suction stress and unconfined strength is established. Under different conditions of the initial degree of saturation and the dry density in soils, the relationship between suction and the degree of saturation at failure can be expressed by a unique soil-water characteristic curve. This result shows a similar tendency to that of a predicted equation using the same parameters for the soil-water characteristic curves. The unconfined compressive strength is also affected by the suction stress which seems to work as a confining pressure for unsaturated conditions. These results demonstrate that the suction stress can be used for estimating the relationship between suction and the unconfined compression test.

  • Measurement of shear modulus for unsaturated silt under one dimensional consolidation state

    S. Kato, S. Shibuya, B. Y. Kim, J. G. Chae, T. N. Lohani

    The shear modulus tor unsaturated silt under one dimensional consolidation state and constant suction state are measured with bender element method. A silt sample under slurry state was consolidated one dimensionally, and desaturated with applying suction. By using the bender element method, we measured the shear modulus for unsaturated soil and examined the effect of suction. From the obtained test results, we find a unique tendency between the normalized shear modulus and the equivalent confining pressure that is the sum of the suction stress and the overburden pressure for both of saturated and unsaturated state. This result implies that the suction stress acts as one of the governing parameters to the shear modulus for a unsaturated silt sample.

    圧密試料及び不かく乱粘土試料を用いて,吸水過程を加えた等方圧縮過程後の低拘束圧下での非排水せん断試験を実施し,有効応力経路とピーク・残留強度に検討を加えた.ピーク強度特性や有効応力経路には,サクションによる弱い粒子間付着力や長期の堆積過程により形成され,構造を生じる強い粒子間付着力が影響する傾向が認められた.また残留強度特性は,サクション応力を考慮すると飽和・不飽和状態にかかわらずユニークに整理される傾向を示した.

  • The model of water retention curve considering effects of void ratio

    K Kawai, S Kato, D Karube

    Water retention curves derived from some initial conditions based on experimental results and some factors affecting the water retention curves are examined. On the drying process of the water retention curve, degree of saturation, water content and void ratio tend to converge to a specific value with increase in suction. And, the value can be regarded as a constant in terms of the water content. The suction value at which the desaturation begins on the drying process from the saturated state is called "Air Entry Value" and depends on the void ratio. The relationship between the air entry value and void ratio can be described as a unique "Air Entry Value Line". On the wetting process, it is found that the shape of the water retention curve depends on the degree of saturation. Likewise, the water entry value on the wetting process can be expressed as a function of void ratio as the "Water Entry Value Line". Thus, in this paper, a new model for the water retention curve adopting the concept of "Virgin Drying Line" presented by Toll is proposed. it is shown that the model can predict the hysteresis loop in the water retention curves when the initial states (suction, void ratio, water content) of specimen are provided.

  • Study of the influence of adhesion force on deformation and strength of unsaturated soil by DEM analysis

    S Kato, S Yamamoto, S Nonami

    In this study, using the distinct element method analysis, simulations of the biaxial compression test for two-dimensional granular material is carried out. In this analysis, the problems encountered in the triaxial compression for unsaturated soil an canceled. The influence of meniscus water in unsaturated soil is reproduced by introducing constant intergranular adhesive force that acts perpendicular to the tangential plane at contact point. The influence of the intergranular adhesive force on the stress-strain relation and the strength constants are examined. From the analytical results, it is found out that the internal friction angle and the cohesion of the assembly of the disk particle increases with the inrergranular adhesive force.

    Deformation behavior of an unsaturated soil in collapse was studied using a modified triaxial test apparatus. Three kinds of wetting test were conducted on compacted clay specimens. (i) wetting tests under isotropic stress state, (ii) wetting tests under constant shear stress, and (iii) repeated wetting during shear test under a constant mean net stress. Collapse occurred later in comparison to isotropic stress state conditions under triaxial stress state when shear stress was kept constant. This phenomenon is due to the decrease of the coefficient of permeability, which relates to the changes associated with bulk water to meniscus water. The relationship between void ratio change and increase in water content observed under the different stress states tested showed similar behavior. In the repeated wetting during shear test, a continuous decrease in void ratio was observed with water absorption and drainage. This phenomenon is also related to the change of the bulk water to meniscus water. The secondary wetting process is observed in the experimental testing program discussed in this paper. The presently available constitutive models do not take into account the secondary wetting process. The research studies presented in this paper provide more insight into the collapse behavior.

  • Deformation characteristics of a compacted clay in wetting tests under isotropic and triaxial stress state

    S Kato, K Kawai

    Deformation in collapse has been studied with a triaxial test apparatus modified for unsaturated soil Two kinds of wetting tests, in which the conditions of suction and stresses were known, were conducted for specimens of a compacted clay. Deformation characteristics in collapses under different stress states were studied and discussed. The relations between void ratio change and increase in water content observed in collapses under these different stress states have the same tendency. And in the case of triaxial stress state, it took several times hours till collapse occurred than that which were needed in the case of isotropic stress state. These test results mean that, after inundation the states of the unsaturated soil is independent of the stress state, but the process of deformation and absorption during wetting process is affected by the stress state.

  • Mechanical behaviour of the unsaturated soil on drying and wetting process under constant net stress

    M Honda, S Kato, D Karube

    Two types of the experimental test results for unsaturated soil are introduced. One is the suction loading and unloading test performed in an oedmeter test apparatus. Based on this results, the influence of void ratio and water content on the moisture characteristic curve is discussed. Another is suction reducing test conducted by a triaxial test apparatus. In this test, each specimen has different hysteresis in suction. The effect of pore water distribution on mechanical behaviour is considered and test results are compared with the theoretical field locus.

  • A constitutive model for unsaturated soils based on the modified ISMP

    S Kato

    This paper aims to present a constitutive model for unsaturated soils, which will explain not only deformation and failure under general stress state but also deformation in collapse, based on the concept of the "Modified ISMP". In this model, we propose yield curves in isotropic stress state, which mean increase in stiffness of soil skeleton induced by increase of suction, and a yield surface which is defined by the condition of a constant plastic work. Two kinds of suction controlled tests are performed on a compacted clay. And it is shown that the deformation in triaxial compression and extension tests under a constant suction and the collapse in wetting test under isotropic stress state agree with the prediction by the proposed model.

  • 不飽和土の圧縮特性に及ぼす間隙水分布の影響に関する研究

    KATO Shoji, KARUBE Daizo, HONDA Michinori, FUJIWARA Teruyuki

    締固め供試体,および予圧密試料にサクションを与え不飽和化した供試体を用いてサクション一定の三軸圧縮試験を行った.等方圧縮過程における両者の挙動を比較することにより,バルク水およびメニスカス水が圧縮挙動へ与える影響を明らかにした.サクション応力を取り込んだ,サクション一定応力条件下における間隙比を与える式を提案し,それに基づいて導かれる等間隙比線について実験結果を検討し,その妥当性を実証した.

  • 不飽和土の間隙水状態と土塊の力学的挙動の関係

    KARUBE Daizo, KATO Shoji, HAMADA Kouichi, HONDA Michinori

    土中の水分量が多い場合は間隙を占めるバルク水が多く存在し,少ない場合はメニスカス水が多く存在すると考えられる.このような水分量の違いの影響を,サクション応力として応力成分に評価する方法を提案した.そして,サクション履歴を与えて水分量の異なる供試体を作製して三軸圧縮試験を行い,メニスカス応力およびバルク応力の合計であるサクション応力の推定値と実測値を比較することにより,その妥当性を検証した.
