Plane Strain Condition Experiments and Elasto-Plastic Finite Element about Collapse Analysis of Retaining Wall by Excavation

Abstract

In a retaining wall with excavation, active earth pressure and passive earth pressure co-exist. There have been few suitable methods concerning the collapse analysis of retaining structure including complex earth pressure conditions. In this study we attempted to clarify the rotating failure of a retaining structure with excavation by the finite element analysis with the implicit-explicit dynamic relaxation method. By comparing the results of model experiments with those of the finite element analysis, we evaluated the applicability of the finite element analysis for rotating failure of the retaining structure. The displacement calculated by the finite element analysis agreed well with those of model experiments.
