摘　　要：采用非饱和土的强度理论提出了一种基坑整体稳定的分析方法 ,在对水泥搅拌桩为支护结构的基坑整体稳定分析中该方法考虑基坑周围非饱和土基质吸力的影响 。Based on the strength theory of unsaturated soil,on analysis method of the overall stability of foundation pit is presented,which considers the effect of additional internal pressure of unsaturated soil around foundation pit in the overall stability analysis of foundation pit where the cement mixed piles are taken as the support structure.The variable law of the safety factor about the ovorall stability of saturated unsaturated soil foundation pit is discussed.

关 键 词：非饱和土 强度 基坑 整体稳定 安全系数
