摘　　要：为对露天边坡稳定性进行科学合理的评价分析,在综合分析露天边坡失稳事故的基础上,采用安全系统工程中的事故树分析法,建立了露天边坡失稳事故树模型。通过计算事故树的最小割集、最小径集和基本事件的结构重要度,找出了导致露天边坡失稳的主要因素,即边坡支护和边坡监测。事故树分析法能够对导致露天边坡失稳的各种因素及逻辑关系作出全面的阐述,并根据结构重要度提出针对性的防治措施,为露天边坡的安全管理提供可靠的参考依据。In order to make scientific evaluation and analysis of open pit slope stability,the fault tree model about the open pit slope instability is established by using fault tree analysis of safety system engineering based on comprehensive analysis of accidents about the open pit slope instability. By calculating minimal cut set,minimal path set and structure importance of basic event,the main factors influencing the stability of open pit slope are found out,that is slope support and slope monitoring. Fault tree analysis can make a comprehensive exposition about various factors which lead to open pit slope instability and logical relationships,and some corresponding prevention measures are put forward. It is a reliable reference for open pit slope safety management.
