Abstract
In order to study the dynamic response law of pile-arch bridge foundation under the action of seismic load, the reconstruction and expansion project of Zhoushantun-Dinghai Highway Xincheng Bridge is taken as an example. The linear finite element analysis software ANSYS is used to establish the linear sum. The nonlinear pile-soil interaction model is used to study the nonlinear time-history analysis of pile-soil interaction system under medium earthquake and large earthquake. The analysis results show that under the action of strong earthquakes, the interaction between pile and soil shows nonlinear behavior, and the soil exhibits obvious deformation deformation. Considering the nonlinear pile-soil interaction, the horizontal displacement of the pile body, the internal force and the internal force are significantly increased, which can provide reference for the seismic design of the pile foundation of the steel box tied arch bridge.
