摘　　要：采用非饱和土的强度理论推导了考虑挡土墙周围非饱和土基质吸力对水泥搅拌桩挡土墙支护结构稳定性状的影响的分析方法,初步探讨了饱和-非饱和土环境下水泥搅拌桩挡土墙支护结构的稳定安全系数变化规律.Based on the strength theory of unsaturated soil, an analysis method of the stability of retaining wall where the cement-mixed piles are taken as the support structure is reduced, which considers the effect of matric suction of unsaturated soil around the retaining wall.The variable law of the safety factor about the stability of the retaining wall, where the cement-mixed piles are taken as the support structure on the saturated-unsaturated soil state, is discussed.
