摘　　要：基于中厚板理论,考虑上部结构、基础与地基三者共同作用,以及土的非线性因素,采用有限单元法,建立全三维模型,分析了筒体结构下桩筏基础中筏板的内力与变形。同时,讨论了筏板内力和变形的影响因素。Based on the mediumthickness plate theory,considering the interaction among upper structure,foundation and soil,also taking the nonlinear factor of soil into account,the three dimensional finite element method is used to analysis the deformation and internal force of raft plate below frametube.In the meanwhile,the influence factor of raft internal force is discussed.
