摘　　要：本文通过对石宝露天铁矿边坡的地质情况和现状进行认真剖析,详细阐述了极限平衡法中的Sarma法的工作原理,并采用Sarma法对石宝露天铁矿中的F区的边坡稳定性进行认真计算,通过计算求出滑动安全系数FJ与标准安全系数Fb比较,判断出边坡的稳定性,并提出安全防范措施,确保安全生产。According to carefully analysis of the geology conditions and current situation of Shibao iron strip mine slope, the principle of the Sarma method which is included in limit equilibrium method in detail is introduced in this paper. At the same time, the slope of F district is computed by the Sarma method. Compared the result of glide safety factor Fj with the standard safety factor Fb, the stability of the slope is determined and the safety precautionary measure.is put forward, then the safety production is ensured.
