| 摘 要： | 首先对深基坑地下连续墙槽壁失稳机理进行探讨,然后基于库仑理论对槽壁整体稳定性进行滑动体受力平衡分析并导出了槽壁稳定安全系数的计算公式,结合算例与半圆柱法、抛物线法以及对比法等进行了对比分析,并对影响槽壁稳定的主要因素进行了分析,最后提出了控制槽壁稳定的一系列具体措施。

| Abstract: | Destabilization mechanism of slurry trench of diaphragm walls in deep excavation was discussed.Based on the Coulomb theory slide mass force equilibrium analysis on the global stability of slurry trench was made and stability factor calculation formula of slurry trench was deduced.Combined with the example,different results were derived by use of the parabola model,cylinder model and correlation method,etc.The effect of different factors on the stability of slurry trenches was given by the calculation formula.At last,a series of specific measures to control the stability of slurry trench were provided. |
