摘要
对深基坑工程中计算柔性挡土结构的弹性支点法作了改进,使之能够考虑柔性挡土结构与土之间的摩擦效应.运用虚位移原理推导出考虑接触摩擦效应的杆单元刚度矩阵,计算结果表明考虑接触摩擦效应时柔性挡土结构的内力及变形都有显著的减小.
In this paper the finite - element method of beam on elastic subgrade is medified to study the contact frictional effect between retaining wall and soil. The element stiffness matrix which can consider the contact frictional effect has been derived by virtual displacement principle method. The computed result show that when the contact frictional effect is considered, the displacement and the stress of retaining wall will be reduced considerably.
