| 摘 要： | 以上覆土层为60 m的主跨为85 m,采用桩承墩基的钢管混凝土拱桥为分析对象,建立三维有限元模型.地基土采用服从Drucker-prager屈服准则的弹塑性模型,并且采用接触对方法模拟土与桩侧面的相互作用,分析了考虑土与结构动力相互作用效应的拱桥地震反应,并与不考虑相互作用的拱桥地震反应作了对比,发现动力相互作用对横桥向反应影响很大.

| Abstract: | Three-dimensional finite element analysis in time domain for dynamic soil pile interaction of CFST(concrete filled steel tube) arch bridge with a main span of 85 m and pile draft foundation was carried out.The elasfic-plastic model of soil was cosidered to follow Drucker-prager yield criterion,and contact pair approach to simulate pile-soil interaction was adopted.The seismic response of CFST bridge analysis result considering soil-structure interaction was compared with that of without considering such interaction.It is obvious that the lateral response is bigger than its longitudinal response with considering SSI effect. |
