ELASTIC-PLASTICITY FEM ANALYSIS OF SOIL-REINFORCEMENT COMPOSITE MATERIAL THROUGH MODEL TEST ON STEPPED REINFORCED SOIL RETAINING WALL

摘要

A mechanical model for soil-reinforcement composite material was built up based on self-consistent theory. And the model simulations were compared with a model test on stepped Reinforced Soil Retaining Wall (RSRW) .The results indicate that the elastic-plasticity FEM Analysis based on soil-reinforcement composite material model could exactly present the initial mechanical characters of soil as well as the capability for engineering.
