摘　　要：以新疆某露天矿边坡为实例,将可靠度理论和模糊数学概念有机地结合起来,利用FLAC及matlab等工具对该边坡进行模糊随机可靠度的综合分析,计算出该边坡的稳定概率及失稳概率;并且对影响边坡稳定的各因素加以分析,对影响边坡可靠度的主要因素进行敏感度分析,最后得出能够指导实践并加以应用的结论。By combining reliability theory with fuzzy mathe- matics, and using FLAC and matlab, a fuzzy random relia- bility analysis on slope stability of an open-pit mine in Xin- jiang was carried out, the stability probability and instability probability of the slope were calculated. In addition, the main factors influencing slope stability were analyzed, the sensitivity analysis on the main factors influencing slope reliability was also carried out. Some conclusions that might guide practical engineering and be applied were drawn.
