| 摘 要： | 上部结构-基础-地基之间相互作用和共同工作问题的研究长期以来是土木建筑工程中非常重要的课题之一.本文采用ANSYS10.0,建立了九层框架结构、筏基和土体共同作用的有限元模型,通过数值模拟计算,比较了共同作用的分析方法与常规计算方法的结果,揭示出结构体系三部分间的相互作用影响和内在联系,研究了地基沉降和基底反力的空间分布,以及基础和上部结构的内力重分布规律,为改进实际结构设计的安全、经济性提供依据.

| Abstract: | Superstructure,foundation and subsoil interact on each other;and the interaction effect has been one of the most important problems in civil engineering.A FEM model consisting of a 9-floor frame,raft foundation and subsoil is built using ANSYS10.0 in this paper.The results from the interaction analysis and the common method are compared by numerical simulation calculation,and the interaction influence and internal relations among the three structure components are investigated.The foundation settlement and ... |
