摘要
针对目前弹性地基梁法和二维平面应变问题有限元法在分析深层搅拌桩墙体的受力与变形中存在的问题,从Mindlin 厚板理论出发,建立了深层搅拌桩墙体受力与变形分析的三维有限元模型。通过对上海珠江玫瑰花园围护结构受力与变形所进行的三维有限元分析与计算。
In the light of the situation that there are problems in analyzing mechanical behavior for deep mixing wall with elastic foundation beam method and two dimensional FEM,the paper sets up the 3 D FE model for analyzing deep mixing wall based on Mindlin's thick plate theory.Moreover the relevant FE program has been also developed.The calculation results indicate that the deformation of deep mixing wall should be the combination of the rotation of a rigid body and the elastic deformation.
