摘　　要：为研究露天采场岩体边坡破坏模式,以某露天矿采场边坡为工程背景,采用RFPA对1-1剖面、2-2剖面进行自然工况和加固工况下的边坡数值模拟。结果表明:2个典型剖面内部岩体以剪切破坏为主,在边坡下方F5断层、X煌斑岩脉与F2断层交叉部位产生大量剪切破坏,形成以F5断层为上盘,边坡岩层分界线和F2断层为下盘的潜在滑动大块体;边坡经过锚索加固措施后,可以改善边坡的局部与整体稳定性。In order to study the failure mode of rock mass slope in open-pit stope,taking the slope in an open-pit mine as the engineering background,the article uses RFPA to conduct numerical simulation of slope at sections 1-1 and 2-2 under natural conditions and reinforcement conditions.The results show that the rock mass in the two typical sections is mainly shear failure,and a lot of shear failure occurs at the intersection of F5,X and F2 faults at the bottom of the slope,forming a potential sliding mass with F5 fault as the hanging wall and the boundary of the slope strata and F2 fault as the footwall.The local and whole stability of the slope can be improved after the anchor cable reinforcement.
