中文摘要：
岩体边坡可靠性分析的关键问题是岩体强度随机分布参数的确定，通过考虑CSIR岩体地质力学分类中的部分指标为随机变量和评分值RMR与Hoek-Brown强度准则参数m、s的经验关系，采用Monte—Carlo随机抽样方法对大孤山露天铁矿南帮边坡岩体强度的随机分布参数进行了研究，获得了岩体强度的随机分布类型和参数，对边坡破坏的风险进行了评价，为获得岩体强度的随机分布参数提供了一条新途径。
英文摘要：
Determining the random distribution parameters of rock mass strength is significant to analyze the reliability of rock mass slope. After considering random variable selected from CSIR classification and the relationship between RMR with parameter m ＆ s of Hoek-Brown strength criterion, random distribution parameters of rock mass strength in Da- gushan open pit mine was researched by Monte-Carlo ran- dom sampling method. Random distribution types and pa- rameters of rock mass were obtained, and the failure risk of the slope was evaluated, which provided a new solution for achieving random distribution parameters of rock mass strength.
