摘　　要：地震荷载作用下桩-土-结构相互作用问题在桥梁抗震研究中越来越受到重视。本文结合工程实例,利用有限元仿真软件ADINA,建立桩-土-结构相互作用的有限元实体分析模型。选取三种时程波作为地震荷载,对在地震作用下桩-土-结构相互作用对桩的沉降位移,桩侧摩阻力和有效应力的影响进行了分析研究,对桩基设计提出了较为合理的建议。The problem of pile-soil-structure interaction under earthquake has been paid more and more attention to the study of bridge seismic . With an example, this paper uses finite element analysis software, ADINA, using the finite element simulation analysis software to establish the pile-soil-structure interaction finite element entitiesanalysis model. The articles selectes three waves as earthquake load, By analysis of the model simulation results, earthquake under the pile-soil-structure interaction of soil and pile settlement displacement pile shaft resistance and effective stress analysis, pile foundation traits response results validate analysis proposed pile-based design rationalization.
