Finite Element Analysis Of Pile-Soil-Structure Interaction Bridge Pile Foundation Under Earthquake

Deep foundation damage has emerged as the main form of seismic damages to bridges during the earthquakes of recent years. Seismic effects on pile-soil-structure interaction analysis is an important part of bridge seismic design research, but usually this incurs a large computational workload. This paper uses finite element analysis software, ADINA, to analyze pile behavior with a restricted set of parameters. Mainly:⑴Choose the DP the model as material constitutive model pile-soil-structureinteraction analysis, select the3D element, using dynamic time history analysis, usingthe finite element simulation analysis software to establish the pile-soil-structureinteraction finite element entitiesanalysis model and simulation analysis.⑵The articles selected taft wave, Ninghe earthquake Tianjin wave and El Centrowave part of the history wave as a simulation model of seismic loading wave, Usingsoftware function of time and the time step input to establish a good model, By analysisof the model simulation results,earthquake under the pile-soil-structure interaction ofsoil and pile settlement displacement pile shaft resistance and effective stress analysis.⑶With an example, in accordance with the requirements of the design units,further study of the seismic loads, pile-soil-structure interaction on the bridgefoundation traits, analysis of the role of response; pile foundation traits response resultsvalidate analysis proposed pile-based design rationalization.
