摘要

在地下连续墙施工阶段采用泥浆护壁技术开挖槽壁的稳定性一直备受关注。通过假定不同的滑动面或滑动体形状，并根据滑动土体的受力平衡分析或单元土体的应力极限状态分析，已经建立了一些槽壁整体稳定性的分析方法。为辨识这些方法的适用性，从理论基础、计算参数的敏感性以及实际应用效果等方面对其进行了对比研究。结果表明，在半圆柱形和三棱柱形滑动体假设基础上建立的槽壁稳定分析方法，能较为合理地评价槽壁的稳定性。

Abstract

The stability of the slurry-supported trench excavations during the construction of a diaphragm wall panel has always been a matter of considerable concern. Some methods of the global stability analysis have been derived from either the force equilibrium analysis or the stress limit state analysis based on various types of slipping surfaces or sliding wedges assumed. In order to discriminate the applicability of these methods

a comparative study of their theoretical bases

parametric sensitivity and practical application effectiveness is carried out. It has been found that the trench stability analysis methods established based on the prismatic and apsidal sliding wedge assumption can estimate reasonably the stability of the trench.
