| 摘 要： | 对白音华三号露天煤矿复合边坡稳定性进行评价。借助理正软件,采用极限平衡法计算的稳定系数为评价指标,通过多因素敏感性分析认为,地震作用、粘聚力、内摩擦角、地下水位和重度等因素对该边坡稳定参数的敏感性依次变小。这一研究结论与工程实际基本相符。

| Abstract: | The stability of composite slope,within first mining area in the 3rd Baiyinhua opencast coal mine,was analyzed.By using the Lizheng software,the stability factor,which was calculated by adopting traditional limit equilibrium method,was considered as an indicator,and the sensitivity of factors,such as seismic effect,cohesion,friction angle,ground-water level and density is smaller in order to the slope stability according to multi-factor sensitivity analysis.The research conclusion coincides with engineering... |
