摘要

Inelastic deformation behavior of ground beneath footing subjected to cyclic loading was predicted by elastoplastic finite element (FE) program in which the extended subloading surface model was incorporated. Considering the translation of similarity center for the normal-yield and subloading surfaces in a plastic deformation process settlement of the footing shook down with increasing number of the loading cycles. It was verified that the settlement and compaction behavior in the simulation qualitatively agree with observed results.
