基于Hoek-Brown准则的岩体力学参数估算及其工程应用
|
摘要
以拉拉铜矿露天矿边坡为工程案例,将岩体工程质量评价RMR法与Hoek-Brown强度准则相结合,利用矿山地质资料和室内岩石力学试验结果,估算边坡岩体力学参数,然后,对露天矿边坡的稳定性进行定量计算与分析,研究成果对该矿安全生产管理有一定的指导意义,对其他类似岩质边坡的稳定性分析有一定的借鉴作用。
Mechanical parameters of rock mass of the slope of Lala Copper Mine were estimated from the mine geological data and the results of laboratory rock mechanics test by combining the RMR method of rock mass engineering quality evaluation with Hoek-Brown strength criterion.Then,the quantitative calculation and analysis of the slope stability of the opencast mine were carried out.The results can guide the safety production management of the mine and can be used as reference for the stability analysis of other similar rock slopes.
