摘　　要：露天矿岩体抗剪强度参数影响边坡稳定和矿山安全,受结构面及地质环境条件影响,岩体抗剪强度很难直接和准确获取。文章通过工程上常用的岩块强度折减法、Hoek-Brown准则法和工程岩体质量分级标准法获得了岩体抗剪强度参数,在分析了各类方法问题的基础上,提出了基于层次分析法的岩体抗剪强度参数的确定方法,计算结果能综合反映岩体抗剪强度参数特征,为全面客观地确定露天矿岩体抗剪强度参数提供参考。The shear strength parameters of rock masses in open-pit mines affect slope stability and mine safety.Due to the influence of structural planes and geological environmental conditions,it is difficult to directly and accurately obtain the shear strength of rock masses.The article obtained the shear strength parameters of rock masses through commonly used rock block strength reduction method,Hoek Brown criterion method,and engineering rock mass quality grading standard method in engineering.Based on the analysis of various method problems,a method for determining the shear strength parameters of rock masses based on the Analytic Hierarchy Process is proposed.The calculation results can comprehensively reflect the characteristics of the shear strength parameters of rock masses,providing a reference for comprehensively and objectively determining the shear strength parameters of open-pit mine rock masses.
