| 摘 要： | 目前对开挖工程一般只作总应力法分析。本文结合某炮和软粘土地基深基坑开挖的工程实例，将Biot固结有限元法用于基坑性状的研究。分析表明，坑壁立体位移和支撑轴力的计算和实测值基本吻合;在土方停挖期，两者均表现出一定程度的固结效应。

| Abstract: | Total stress method is a general method used to analyze the excavation problem- In this paper, finite element method coupled with Biot consolidation theory is used to simulate the behavior of a deep excavation case in saturated soft clay. The computed soil deformations and axial forces in horizontal bracings agree quite well with those through measurements. Both of them indicate that the consolidation effects are rather obvious afer excavation. |
