摘要
对上覆土层为60m的某主跨为85m,采用桩承墩基的钢管混凝土拱桥建立了三维有限元模型,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相互作用,得出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桥梁地震反应做了对比,得出了一些有益结论。
Three-dimensional finite element analysis in time domain for dynamic soil-pile interaction of CFST arch bridge with a main span of 85m, pile groups is carried out in this paper. The model of soil is Drucker- prager, and contact pairs is used. By comparing the result considering SSI and without considering SSI, some advisable conclusions are derived.
