Research Abstract

This study focuses on two topics. One is stability evaluation of soil structure for dynamic loading as earthquake. The other is evaluation on residual deformation of soil structure caused by dynamic loading.
The seismic coefficient method has been employed to estimate a stability of soil structure for a dynamic load the direction and the magnitude of which vary in time. But, it can not consider an acceleration time history of an earthquake and dynamic properties of both soil structure and ground. This study presents a new analytical method to estimate a stability of soil structure for a dynamic loading as an earthquake taking acceleration time history into account. The applicability of this method to design is discussed.
On the other hand, rigid plastic dynamic deformation analysis is developed to evaluate a residual deformation by an earthquake loading. In a rigid plastic assumption displacement is generally in determinate. It is, however, rationally determinate in concern with a prescribed acceleration on the boundary. Typical numerical examples are shown for embankment problems under earthquakes.
