摘　　要：本文论述了边坡“破坏”这一概念本身所具有的模糊性,提出将边坡破坏按模糊准则划分为苦干等级,并给出了各破坏等级的隶属函数。结合边坡工程中存在的随机性,定义了边坡工程对于各破坏等级的可靠度,得出了相应的计算公式,为边坡稳定性评价提供了一条新的途径。文末对一个实际边坡进行了可靠度计算和稳定性评价。In this paper,the author expounded the fuzziness in the slope failure,put forward an idea that the failure can be divided into several grades according to the fuzzy standards,and provided a subordinate function of each grade.Considering the random property existing in slope engineering,the writer defined the reliability of each failure grade and came to a formula for calculation,provided a new way of evaluating the slope' s stability and used it to calculate a practical rock slope' s reliability and to evaluate the slope' s stability.
