摘　　要：岩石样本值既存在随机性,又存在模糊性。用随机-模糊处理方法和传统方法对边坡工程中的岩石力学参数进行分析,通过对比可知采用随机-模糊处理方法优于传统方法。此外,对岩体力学参数取值置信度进行了探讨,讨论了岩体力学参数的概率分布形式,提出"置信阈值"的概念,从而为随机-模糊方法在工程实践中的应用奠定了基础。The values of rock sample are random and fuzzy.Both of the random-fuzzy approach and the traditional method were applied to analyze the mechanical parameters of slope engineering.After comparison,it is concluded that the random-fuzzy approach is superior to the traditional method.Also,the confidence degree and probability distribution form of mechanical parameters were discussed.Then,the confident threshold concept was proposed so as to provide a foundation for its application in engineering practice.
