摘要
结合大型有限元软件ANSYS,建立了筏形基础 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.
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.
