摘　　要：以可靠性理论为基础,建立了滑坡失稳概率计算模型,给出了基于Bishop法的滑坡灾害危险性概率的计算方法,并以实例分析了该方法的应用,结果表明该方法能较好地定量评价滑坡灾害的危险性。该研究成果对滑坡灾害的评价与防治有一定的参考意义。On the basis of reliability theory, a probability model of stability computation of landslide was set up, and the Bishop-based computational method for hazard probability of landslide was adopted in this paper, and its application was discussed in detail. The results indicated that the hazard of landslides could be fairly bettered evaluated by the method. The research achievement had reference significance for the evaluation and treatment of landslide hazard.
