摘　　要：应用极限平衡法推导出当无粘性土坡部分浸水时,其滑动面为两直线组成的折线形滑动面稳定安全系数的计算模型,并提出确定最小安全系数以及相应滑动面的方法。通过实例分析表明,其计算结果符合工程实际。A model for the calculation of the safety factor for the stability of the fold-lined sliding surface consisted of two straight lines, when part of a cohesionless soil slope is inundated, is educed herein with the limit equilibrium method, and then a method for determining the minimum safety factor and the corresponding slip-surface is put forward as well. Through the analysis on an actual case, it is demonstrated that the calculation result is accorded with that of the reality concerned.

关 键 词：极限平衡法 无粘性土坡 折线形滑动面 安全系数
