摘要
对深基坑挡土结构地下连续墙的弹性支点法作了改造,提出了能考虑地下连续墙与土之间摩擦效应的分析方法。运用虚位移原理,推导出考虑接触摩擦效应的杆单元刚度短阵,计算结果表明新的方法比传统的弹性支点分析法更为合理。
The finite element method of beam on elastic subgrade is modified to study the contact frictional effect between diaphragm wall and soil. The element stiffness matrix which can consider the contact frictional effect of diaphragm wall has been derived by virtual displacement principle method. The computed resuit shows that the method of this paper is more reasonable than the traditional finite element method of beam on elastic subgrade when the spatial effect of diaphragm wall must be considered.
