Finite Element Analysis on Pile-Soil Interaction of Pile under Horizontal Load

A finite element analysis method is adopted to conduct numerical simulation on single pile under lateral load test,the effects of surrounding soil are replaced by soil springs and a new method is put forward for soil spring stiffness derived from test data.This method can be applied in various pile-soil interaction circumstances with different loading and soil surface gradients.The calculation results indicate that the finite element simulation results are basically consistent with the experimental measured data,which can provide an important theoretical basis for engineering practice and design.
