摘要
为了研究水平荷载作用下上部结构—基础—地基共同作用的问题,对整个结构进行了三维有限元数值模拟,建立了水平荷载作用下高层框架结构—桩筏基础—地基共同作用分析模型。针对一具体结构进行研究,采用共同作用方法分析了上部框架结构的水平位移和底层柱的内力,并与常规方法进行比较;同时研究了桩径的变化对上部结构水平位移的影响。通过分析对比,得出有益的结论,供工程设计参考。
In order to find a salution to the problem of a superstructure-foundation-soil interaction on the lateral loading , a 3d numerical technique for the whole structure analysis is used. Moreover a high rise frame structure, pile-raft foundation and soil interaction model is described. By studing a given building, this paper concretely computes： the super-structure lateral deformation and frame internal force by comparing the interactive with the traditional method; the super-structure lateral deformation by c comparing the results, we can draw some interesting conclusion. And the analysis method hanging pile diameter. By analyzing and results may be useful in practical design.
