According to the soil parameters from the survey report and the structural construction drawings of a high-pile pier in Guangzhou, this paper establishes a three-dimensional finite element model of the highpile pier, including the platform, piles, and soil. The surface-to-surface contact model is used on the pile-soil interface, and it allows separation and slip on the interface. The normal pressure and friction from the soil to the piles are reflected by the contact stress. This paper analyzes and figures out the stress fields and displacement fields of the high-pile pier, as well as the axial force diagram and moment curve of single pile, under various load combinations. Further, this paper compares the finite element method results with the traditional inserting point method results,taking Fenghai high-pile pier computing program for example. The differences of the axial force diagram and moment curve of single pile of both methods are found out and analyzed. Specifically, the impacts of the pile foundation soil on the structure are analyzed. Meanwhile, this paper finds out the pile which has the maximum internal force and the position where the extremum bending moment and axis force appears in a single pile, and provides some modifications and supplements for the results of the traditional inserting point method, which may provide references for structural design of high-pile pier.
