摘要: 岩体力学参数取值方法成为了边坡稳定性分析的关键技术。以某露天矿山边坡岩体力学参数取值研究为例,开展室内试验得到岩石的单轴抗压强度、抗剪强度,抗拉强度、弹性模量以及泊松比,并在此基础上采用ROD法和 CSIR 法对岩体质量进行评价,再结合 Hoek-Browm 强度准则对岩石力学参数进行折减,得到的岩体力学参数与实际现场原位试验得到的结果特征基本一致。

关键词: 露天边坡, 岩体力学参数, 岩体质量评价, Hoek-Brown 强度准则

Abstract: The method of selecting mechanical parameters of rock mass has become the key technology ofslope stability analysis. Taking the study on the mechanical parameters of slope rock mass in an open-pilmine as an example, the uniaxial compressive strength, shear strength, tensile strength, modules of elasticity and poisson ratio of rock blocks were obtained through laboratorv tests. On this basis . the rock massquality was evaluated by ROD method and CSIR method, and the rock physical and mechanical parame-ters were reduced by combining with Hoek-Brown strength criterion. The rock mass parameters obtainedwere basically consistent with the characteristics of the actual in-situ test results.

Key words: open-pit slope, mechanical parameters of rock mass, rock mass quality evaluation;Hoek-Brown strength criterion
