    Drainage measures for embankments against rainfall are different during construction and after commencement of use, and the effects are sustained intermittently from the start of construction to after the commencement of use. Of the rainfall over this span of time, it is considered that embankments are undermined internally by the effects of the rainfall during construction. However, as the dates of construction of embankments cannot be determined and the amounts of rainfall sustained during construction are varied, the effects of rainfall on the initial stress conditions upon the completion of embankments have not been clarified. In this study, soil/water/air-coupled F.E. analysis was used to perform analyses of embankments which take into account compaction and the history of rainfall/evaporation, and a comparative study is made of the effects of differences in the amount of rainfall during construction on the initial stresses inside embankment.

    The present work explains the statics of self-weight transmission restricted to a long prismatic heap inclined at an angle of repose and symmetrically formed on a rigid base. The closure of polarized principal axes with the mobilized state of stress along the slope surface is employed by imposing the orientation of principal stresses on the equilibrium equations. Comparisons were made with calculations based on the finite element method using an elastic model. Moreover, experiments on sand heaps deposited on a rectangular rigid base were conducted to validate the theoretical study. The measured pressure profile generally agreed well with theoretical results. © 2014 The Chinese Society of Theoretical and Applied Mechanics.

    The East Japan Earthquake and Tsunami caused serious damages in the coastal area of eastern Japan. Many houses and cars on the road were swept away by the tsunami. Also, industrial facilities such as chemical plants in the coastal area were completely destroyed. Damage from saline seawater was not limited only to the rice field areas, and there were also serious anxieties regarding the possibility of ground contamination as a result of harmful heavy metals that leaked from destroyed chemical plants. In light of this scenario, we carried out a quantitative survey to examine these areas. This paper reports on the results of our survey. It was found that high salt concentrations were detected on the ground surface but predictions state that these concentrations can be diluted with rainfall. It was also revealed that serious ground contamination due to the harmful heavy metals was not detected.

    Embankments are constructed with compacting soil with the aim of improving their stability and deformation characteristics. Typhoons and guerrilla rainstorms are occurring frequently due to the abnormal weather of recent years, and there have been many reports of cases of collapses of embankments due to their effects. Drainage measures for embankments against rainfall are different during construction and after commencement of use, and the effects are sustained intermittently from the start of construction to after the commencement of use. In this study, soil/water/air-coupled F.E. analysis was used to perform analyses of embankments which take into account compaction and the history of rainfall/evaporation. Further, changes in the stresses inside the embankment by the effects of rainfall sustained after commencement of use are considered.

    Results obtained in a lab compaction test are difficult to apply to the design and compaction control at an actual geotechnical engineering site. This is attributed to the fact that the mechanism for compaction has not been explained using the principles of soil mechanics. The main theme of this study is interpretation of the compaction mechanism with unsaturated soil mechanics. Here, static compaction tests were simulated with soil/water/air coupled finite element analysis code DACSAR-MP. Consequently, the shape of the compaction curve was successfully expressed. Moreover, the effects of compaction on compressibility and permeability of compacted soil could be reasonably explained. Additionally, shear deformation was applied to the specimen obtained from static compaction simulations in soil/water/air coupled analysis. The relationships between shear strength and compaction curve showed good agreement with the actual behavior.

    Compacted soil is widely used to build earth structure. Although construction management of the soil progresses day by day, it is said that mechanism of compaction effect isn't fully made clear. This is due to the complication of compaction mechanism of unsaturated soil. Recently, some constitutive models for unsaturated soil and SWCC models were proposed and advanced the study on unsaturated soil. In this study we regarded compaction as the consecutive cycle of compression and expansion of unsaturated soil under undrained condition, and simulated it with unsaturated soil/water/air coupled finite element analysis. In this study, we expressed the characteristics of the mechanical behavior of compacted soil, which has not been explained for a long period of geotechnical engineering. And we considered the difference of compaction procedure affected the quality of earth structures. The achievement can be managed reasonably the compaction of earth structure.

    Desertification due to salt damage has recently become a serious problem throughout the world. Salt damage is a phenomenon where salt in the groundwater gets concentrated at the ground surface and kills vegetation. In this study salt damage due to disequilibrium of water balance was simulated with unsaturated soil/water coupled simulation code, as applied the material transport equation. Evaporation and precipitation cycles were applied to a model of ground that contained salty groundwater in its deep region. This allowed the successful reproduction of the phenomenon of salt accumulation on the ground surface. Additionally, identical climatic conditions were applied to model grounds consisting of two types of soil, different in terms of their soil-water retention characteristics. It was found that two methods of overlay and insertion of a layer of coarse-grade material, known as 'mulching', are effective in the prevention of salt accumulation. © 2011 Taylor & Francis Group, London.

    The ground pollution is one of the most serious environmental issues all over the world now. Industrial wastes discharged from various human activities infiltrate to the ground, diffuse and damage to plants and animals indirectly. Therefore, it is strongly requested to know the transfer behavior of contaminant movement in the ground. In this study, continuous equations and advection-dispersion equation are derived from mass conservation laws in soil, water, air and dissolved material phases. These governing equations are applied to the constitutive model for unsaturated soil and formulated in the framework of the initial boundary value problems with the finite element method The soil/water/air coupled analysis program, DACSAR-M_ad, applied mass transfer equation to is coded. Here, the mass within the ground due to loading is simulated with this code.

    To predict the long-term elasto-plastic behavior of unsaturated earth structures, a constitutive model, which can express the following typical mechanical behavior of unsaturated soil, is needed. This includes shrinkage and increase of stiffness upon drying (i.e. suction increase), collapse with reduction of stiffness upon wetting (i.e. suction decrease), and the influences of suction history related to the hysteresis of soil-water retention characteristics. In this study, a new constitutive model is proposed for unsaturated soil where the effective degree of saturation is used as a parameter relating to stiffness. The model shows good agreement with experimental results. In addition, a soil/water coupled finite element simulation code (simulator), as applied to this model, is introduced. The appropriateness of the simulator is demonstrated for the case of a virtual fill.

    When troublesome sludge discharged from industries and purification plants are burnt by 1300 degree, they change to innocuous micro-porous ceramic materials. The authors are seeking for practical use of such micro-porous ceramic materials in the geotechnical engineering field, particularly for geohazard mitigation. Then, in order to grasp fundamental mechanical properties of the micro-porous ceramic particles, a series of laboratory tests, that is, triaxial compressive shear tests, permeability tests and water retention tests, were performed. It is found that the stress-strain characteristics and permeability of the micro-porous ceramic particles are very similar to those of standard sandy materials but they have very high water retention capability. Next, applicability of the unsaturated elasto-plastic constitutive model proposed by Ohno et al. (2007) to the mechanical behavior of micro-porous ceramic particles was examined in this paper.

The applicability of the Prediction-Method is shown by calculating a bearing capacity simply, using it. The partial drainage shearing tests that use clay and intermediate soil are done, choosing both one side and both sides drainage condition, changing the shear strain speed. As a result, the tests have changed the drainage distance. The relations between the regularized shear strength and the relative shear strain speed was shown ,using one side and both side partial drainage shearing test results separately.

    This study aims at making aggressive contribution of geotechnical engineering to the global environmental problems, through the technical proposal of desertification deterrence against salt damage. As to desertification, over-logging, overgrazing and salinization are the three major factors, accounting for the approximately 80% of entire desertification. It is caused by the deviation of the water circulation between the aerospace and the ground due to deforestation, especially the desertification due to salinization is caused by high concentration of salinity, basically diluted in the underground water. Such salt damage is observed in a wide range of areas of the Eurasian continent. In this study, a FE simulator which can represent the desertification mechanism by such salt damage is developed and a salt damage deterrence construction method is developed with taking account of utilization of granular materials such as recycling of PS ash and water purification plant sludge.

    Soil compaction is important when constructing earth structures. However, we have had difficulties in presuming the internal state of earth structures and predicting their behaviors under natural disaster such as storm of rain and earthquake. In this study, simulated static compaction tests and processes of compacted earth structures considering the speed of construction with soil/water/air coupled finite element analysis. The achievement of this study is useful for the reasonable construction management.

    It is well known that salt rock layer is widely deposited under the Eurasian basement. Underground water contains weakly salt where the salt rock layer is occasionally deposited near the ground surface. Such a typical example can be seen in the northeast area of Thailand. Agricultural productivity decreases due to the salt damage of that the salty ground water level gradually rises resulting in appearance of salt crystals on the ground surface associated with annual repeat of rainy and dry seasons. This research project is intended to develop a numerical computation technique to reveal the mechanism of salt damage which will lead desertification. On the other hand, paper sludge discharged from paper manufacture causes a serious environmental problem. Such sludge can be changed to porous stable ceramic materials by burning it at 1300 degrees. This research project also aims at utilizing such materials to protect and repair the salt damage.
