In the pile driving process, the soil dynamic performance and the dynamic contact on the interface are very complex. In order to analyze the interactions between the pile and soil, the simulation model of the pile-soil system is created by the finite element software. The numerical solution and the displacement curves of the pile are obtained based on suitable parameters of the pile-soil system and the D-P criterion. Then the amplitude and the frequency of the exciting force as well as the stiffness and the damping of the soil are changed to obtain the displacement curves of the pile. Through the comparisons between the curves, the influences on the pile driving process coming from the exciting force and other parameters are found out.
