Research Abstract

This sutdy developed two methods to evaluate the stability of soil structures. One is a stability analysis which deals with the limit state of structures and the other is a dynamic deformation analysis to examine the residual deformation of structures against earthquakes. In stability analysis, a new safety concept is proposed against dynamic loads and shown to give rational factors of safety through some numerical examples. It could consider the effect of acceleration time history of earthquakes. On the other hand, in dynamic deformation analysis rigid perfectly plastic assumption is employed. It is exhibited to yield good solutions for large deformation problems. The effect of geometrically change of structures on the deformation is discussed. For liquefaction problems, an excess pore water model for earthquake is introduced after Carter et al.. The liquefaction process is well simulated with this method.
