摘要
通过编制非线性有限元分析程序 ,研究浅基础下设变刚度垫层地基土中应力分布、变形性状 ,变刚度垫层的设置 ,使得基底反力向基底中部集中 。
The stress distribution and deformation in soil under shallow foundation with variable stiffness cushion are studied by means of nonlinear finite element analysis, by the variable stiffness cushion, the contact pressure is concentrated toward the center of shallow foundation and the ultimate bearing capacity of foundation soil is increased.
