摘　　要：基坑开挖采取的降水措施会引起土体内部含水量的变化,进而影响其抗剪强度参数的变化,文章结合试验结 果分析了含水量因素对土的强度影响,并提出粘聚力及内摩擦角的具体计算公式,对于边坡稳定以及地基承 载力计算具有一定实践意义。Pumping consolidation in deep excavation would cause a change of water condition and also take an effect on the parameter of shear strength. According to the results of laboratory test, this paper analyzes the effect of water content on the strength of soft soil, and puts forward to an formulation about the coherent strength and the friction angle respectively, which would contribute to calculating the stability of slope and the ability of foundation bearing capacity.
