—Presented is the numerical analysis of settlements of soft soil by a 2-D dynamic effective stressFEM method.The model based on the results of cyclic triaxial tests on the reconstituted soft Ariake clay isused to predict the wave induced excess pore water pressure and residual strain of soft clay.The settle-ments of two types of breakwaters on the soft clay under ocean wave load,a low embankment subjected totraffic load and the tunnel surrounded by soft clay in Shanghai subjected to locomotive load are calculatedas examples.
