| 摘 要： | 结合大型有限元软件ANSYS，建立了筏形基础一地基相互作用体系的全三维有限元模型．考虑土体的弹塑性性质，模拟基础和地基交界面上的状态非线性，采用中厚板理论分析筏板，对筏形基础的受力进行了非线性数值分析．结果表明，考虑地基非线性特性时，地基反力及基础沉降的计算结果更接近实际．

| Abstract: | Using general-purpose finite element program ANSYS,a three-dimensional finite element model of interaction between raft foundation and groundwork soil is established.Considering elastoplastic property of the soil and simulating the nonlinearity condition of soil-foundation interface,non-linear numerical analysis is performed based on the medium-thick plate theory.The computation results show that the subgrade reaction and foundation settlement are coincident with test data. |
