摘　　要：本文将可靠度理论应用于边坡倾倒式破坏分析,根据后缘裂隙发育深度判定其破坏概率;将倾倒式破坏极限状态函数作为功能函数,以后缘裂隙充水高度作为随机变量,引入可靠度理论,结合Matlab数学软件,进行多次抽样,分析不同裂隙发育深度时边坡的破坏概率。该分析为后期治理工程的设计提供关键参数,对工程设计实践具有重要意义。In the paper,reliability theory is applied in slope dumping damage analysis. The failure probability is determined according to trailing edge fracture development depth. The dumping failure limit state function is used as a performance function. Trailing edge fissure water filling height is used as random variable. Reliability theory is introduced.Matlab mathematical software is combined for multiple samplings. Slope failure probability of different fracture development depths is analyzed. The analysis can provide key parameters for design of subsequent control project. It has important significance for engineering design practice.
