| Abstract: | In this paper,by using finite element program ANSYS,the three-dimensional finite element numerical simulation on the lateral nonlinear response of pile group is discussed.The significant effect of the nonlinear soil behavior and the pile-soil interface separation on the response of pile group are studied in this model.Through comparing original test,the correctness of the model is validated.The nonlinear response of the pile-soil interaction is analyzed based on the model,and valuable conclusions are obtain... |
