【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。更多还原

【Abstract】 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.更多还原
