Seismic Responses Study of Pile-groups Foundation

The pile foundation is a widely used form of the basis, and its mechanical behavior under static action has been basically clear, but has yet to be a more detailed study of response pattern under dynamic action. A group pile foundation for the study, with the dynamic finite element analysis method to explore the seismic response law of pile groups. The study considered the nonlinear soil, pile - soil interaction, pile side resistance and end resistance action. Calculated dynamic response results of the cap - Piles foundation system, and it's research findings have reference value to the dynamic design of the pile foundation.
