Outline of Final Research Achievements

Deformation and failure pattern due to the large earthquakes have been investigated and the effect of the ground has been clarified. The deformation characteristics of unsaturated soil of levee were studied using the triaxial tests and the FEM numerical codes for the air-water-soil three phase dynamic analysis were been developed. Uisng the developed new method, we have clarified the deformation and strain localization characteristics of levee on the clayey ground. The duration time of earthquake is an important factor of the disaster of levee due to large earthquakes. For the construction of infrastructure to prevent disaster of the river embankments,we need the dynamic analysis of levee using the new analysis method developed in this study.
