中文摘要：
如何可靠的获取岩体的力学参数,一直是岩体力学界研究的重要课题。本文采用RMR分类方法、Hoek-Brown强度准则,获得了边坡稳定性计算分析所用的摩尔库伦模型基本参数,实现了室内岩石力学实验参数与野外现场实际岩体参数的过渡与衔接。并以某露天矿岩质开挖边坡典型剖面为例,进行该边坡岩体力学获取及开挖稳定性分析,计算结果表明：对于所计算的剖面边坡,应注意对露天采矿坑底、边坡坡脚处进行有针对性的治理工程,以保障矿山的安全生产。
英文摘要：
Acquisition of reliable rock-mass mechanical parameters is always a key issue in the research of rock-mass mechanics. In this paper,were combined with rock mass rating（ RMR） classification and HoekBrown Strength Criterion to acquire the basic Moore Coulomb model parameters for computation and analysis of slope stability. We also achieved the transition and connection between the indoor experimental mechanical parameters and the in-field actual parameters. With the typical sections in an open-pit rocky excavation slope as example,we acquired the rock-mass mechanical parameters and analyzed the excavation stability. The results show that in computation of sectional slopes,the targeted engineering treatment should be applied to the open-pit mining bottom and slope toes,thus guaranteeing the safety production in the mine.
