| 摘 要： | 考虑到墙周土体及接触的非线性,借助Mar软件建立了空间三维有限元模型,通过与工程实测比较,证明模型合理;在此基础上分析了土体变形模量、泊松比及墙土接触的摩擦对地下连续墙基础沉降的影响,结果表明:土体变形模量对基础沉降的影响相当大,泊松比取其经验值对基础基本无影响,墙土间摩擦系数的提高对基础沉降的减小有一定的作用。

| Abstract: | This paper deals with the influence of wall soil parameters on numeral simulation for settlement of underground diaphragm wall foundation with the aid of 3-dimensional finite element model. The results indicate tremendous influence of Eo on foundation settlement and no influence of Poisson＇s ratio on foundation settlement and decrease in foundation settlement of increase in ~t. |
