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 ,提出了考虑柔性挡土结构与土之间摩擦效应的分析方法。计算结果表明考虑摩擦效应时柔性挡土结构的内力及变形都有较显著的减小。
The finite element method of beam on elastic subgrade is modified to study the contact frictional effect between retaining wall and soil. The element stiffness matrix that can consider the contact frictional effect is derived by the virtual displacement principle method. The computed result shows that when the contact frictional effect is considered, the displacement and the stress of retaining wall will be reduced considerably.
