在软土深基坑开挖的有限元模拟中,诸多因素影响着基坑开挖的侧向位移。本文在总结分析前人关于这些影响因素研究的基础上,重点指出:土体静止侧压力系数k0对正常固结和弱超固结软粘土基坑侧向位移有重要影响,并定性分析了k0对此土体条件下基坑侧向位移的影响,为其定量化研究奠定了基础。
In the finite element simulation of deep excavation of soft soil, many factors affect the lateral displacement of excavation. Based on the analysis of previous studies on these influencing factors, this paper points out that the static lateral pressure coefficient k0 of the soil has an important influence on the lateral displacement of the normal consolidation and the weakly overconsolidated soft clay foundation pit, and qualitatively analyzes the k0. The influence of the lateral displacement of the foundation pit under this soil condition laid the foundation for its quantitative study.
