摘要
针对某一明挖基坑工程进行施工过程三维动态数值模拟分析,获得了不同开挖工况下土体的应力状态、地表沉降、坑底隆起、支护结构的受力与变形情况。对于地质条件相差不大的狭长基坑工程,采用分段动态数值模拟计算分析,对后期围护结构的优化设计与指导施工具有重要意义。
The three-dimensional dynamic numerical simulation analysis of the construction process of a certain open excavation project was carried out in this paper,and the stress state of soil,surface settlement,uplift of pit bottom,stress and deformation of the supporting structure under different excavation conditions were obtained.For the long and narrow foundation pit with little difference in geological conditions,the piecewise dynamic numerical simulation analysis is of great significance for the optimal design and construction of the surrounding structure in the later stage.
