| 摘 要： | 为探讨在工程上简便实用的从三维空间角度来整体分析深基坑支护体系变形状的有效方法，对基坑支护结构的连续介质三维有限元模型进行分析，得出了分阶段开挖情况下基坑混合支护体系空间变形的性状，并与按一次性开挖的分析结果进行了比较，从分析结果可知，支护结构上部的位移计算结果与理否考虑开挖掘的阶段性有关关系，而按空间问题还是平面问题来分析，角点附近的位移计算结果有较大判别。

| Abstract: | To research the practical effective method of 3D analysis of bracing structures of deep foundation pit, the space deformation behavior of synthetic bracing structure, under the case of by stages excavation is obtained, and compared with the conclusion under the case of by onetime excavation, according to analyzing 3D FEM(Three dimensional finite element method) model. The analyzing result shows that the calculating result of displacement of upper bracing structures relates to whether the stage of excavation is taken account into or not. There is considerable difference of the calculating results of displacement around joints between by space analyzing method and by plane analyzing method. |
