摘　　要：详细统计并分析了乌恰地区近几十年的地震数据,确定了乌拉根铅锌矿不同年限下发生地震的概率以及加速度选取值,研究了乌拉根铅锌矿边坡风险等级以及不同工况条件下的安全系数。在充分考虑地震偶发性的工况前提下,计算不同分区剖面的边坡稳定性系数,根据计算结果对当前边坡结构参数进行优化。Based on the detailed statistics and the analysis of the seismic data of the Wuqia area in recent decades,and determine the probability of earthquakes and the selected values of acceleration in the Wulagen lead-zinc mine under different ages,study the slope risk grade and safety factor under different working conditions in the Wulagen lead-zinc mine.Under the premise of fully considering the accidental seismic conditions,the slope stability coefficients of different sub-sections are calculated,and the current slope structure parameters are optimized according to the calculation results.

关 键 词：边坡稳定性 安全系数 地震加速度 边坡角优化
