摘　　要：以广西某高岭土露天矿为工程实例,通过室内岩石力学实验和现场工程地质调查相结合,采用RQD和RMR法对边坡岩体进行岩体质量评价,基于广义Hoek-Brown准则利用RocLab软件计算边坡岩体力学参数,基于极限平衡法利用Slide软件对最终边坡三种工况的稳定性进行分析。结果表明:最终边坡稳定性较好,采场边坡参数选取可行,可为同类矿山提供参考。计算结果为矿山的边坡防护与治理提供依据。Taking a kaolin open-pit mine in Guangxi as an engineering example,through the combination of indoor rock mechanics experiment and on-site engineering geological survey,RQD and RMR methods were used to evaluate the rock mass quality of slope rock mass,RocLab software was used to calculate the mechanical parameters of slope rock mass based on the generalized Hoek-Brown criterion,and the stability of the three working conditions of the final slope was analyzed by Slide software based on the limit balance method.The results show that the final slope stability is good,and the selection of stope slope parameters is feasible,which can provide reference for similar mines.The calculation results provide a basis for slope protection and treatment of mines.
