摘要
针对安家岭露天煤矿黄土高台阶边坡，综合应用现场工程地质调查、力学试验、稳定分析等方法对黄土高台阶边坡稳定性进行评价。根据现场工程地质调查及岩石特性，选取安家岭露天矿北帮9800～10050区段xP1剖面、xP2剖面，通过计算得出典型剖面黄土高台阶处整体稳定系数均不满足安全储备系数要求的结论。综合分析多种因素，确定采用削坡减重处理方法，治理后稳定系数分别为1．310和1．24l，均满足安全储备系数1．2的要求。
For the loess high step slope of Anjialing Open -pit Mine, field engineering geological survey, mechanical tests and stability analysis were used to evaluate the stability of loess high step slope. According to the field engineering geological survey and rock prop- erties, choosing XP1 and XP2 profiles from 9 800 -10 050 section in the North of Anjialing Open - pit Mine, the whole stability coeffi- cient of typical loess high step slope do not meet the safety requirements of reserve coefficient. Through analyzing various factors, the treatment method of slope cutting and reducing weight is determined. The stability coefficients after treating 1. 310 and 1. 241 respec- tively, which meets the requirements of safety reserve coefficient.
