无支护基坑侧移空间效应分析
摘要:针对基坑变形存在的空间效应,运用有限元分析软件ANSYS,对无支护结构情况下的基坑开挖过程进行数值模拟,分析了随开挖过程基坑壁侧向位移在水平和深度方向的分布规律,针对基坑坑角变化对基坑位移的影响进行了探讨,并对基坑壁位移的分布函数进行了讨论,得出一些有益的结论,为基坑工程设计与施工提供参考。
Abstract:For the three-dimensional effects caused by the excavation, the finite element software ANSYS is used to simulate the excavation process of a foundation pit with non-supporting structure. The distribution of the pit ground lateral displacement with every step of excavation was analyzed. The influence of the different angles of the pit on ground lateral displacement was studied. And, a distribution function of the pit ground lateral displacement was discussed. Some useful conclusions were obtained and the results may provide reference for the excavation design.
