摘要
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。
There are many factors which affect the lateral displacement of excavation when using the FEM to analyze it. This paper reveals that the earth pressure at rest ( k0 ) has important affect on the lateral displacement of excavation on the basis of other scholars' research. The qualitative analysis of the influence of the affecting factor ( k0 ) on the lateral displacement of excavation is the transition to the quantitative analysis.
