Soil water coupled analysis of soil behavior under breakwater during water action was performed using SYS Cam-clay model. In fact under cyclic loading, the plastic strain goes on regardless the state of overconsolidation. In this model, the cyclic plasticity was introduced, so that it can be explained the accumulation of plastic strain.
The soil resistance of shear strength under breakwater was investigated supporting the typical clay soil. Acted on the static force to the breakwater, the relation between force and horizontal displacement was shown. Compared with the safety ratio of port standard, some good correspondence was obtained.
