大冶铁矿狮子山岩质边坡稳定性评价

针对大冶铁矿东露天狮子山北帮最终边坡工程地质条件，采用极限平衡理论3种不同的分析方法进行稳定性计算和CSMR法对边坡进行岩体质量评价。结果表明，边坡安全系数均大于1，基本处于稳定状态；除边坡西部中上部岩体质量为Ⅲ级,稳定性一般外，其余区段为Ⅱ级,稳定性好。分析结果与边坡目前的稳定性状况一致。

Stability Evaluation of Shizishan Rocky Slope in Daye Iron Mine

In light of the engineering geological conditions of the final slope of Shizishan north wall in the east open pit of Daye Iron Mine, three analytical method of limit equilibrium theory were used in the stability calculation and CSMR method was used in the evaluation of rockmass quality. The results indicate that the slope safety coefficient is all greater than 1, representing a stable status; and the rockmass quality is of Grade II that represents a good stability, except the rockmass in the middle and upper part of the west slope which is of Grade III that represents a general stability. The analysis results accord with the present real slope stability conditions.
