深基坑开挖中地下连续墙侧向位移计算的变分解法

Variation Methods Used to Calculate Side Displacement of Retaining Wall in Deep Excavation

目前对深基坑开挖中挡墙侧向位移多采用有限元法进行计算 ,试用弹性力学的有关理论对某一工况的地下连续墙侧向位移进行分析 。

The finite element method(FEM) is usually used to calculate side displacement of retaining wall in deep excavation. Herein the interrelated theory of elasticity mechanics is opted for analyzing the side displacement of underground diaphragm wall. The practical example indicates that the calculation value can be better coincided with the actual test value.
