| 摘 要： | 由于黄土边坡破坏（失效概率）的不确定性，煤矿区工程建设多忽略矿区黄土边坡的稳定性，加上煤矿区边坡的特殊现状，边坡事故时有发生。通过对山西省40处煤矿区黄土边坡的双参数统计分析，探寻边坡存在自然风险的内在机理。首先，按岩土结构组合特征将边坡分成4种地层结构模型；在此基础上，重点统计分析了各结构模型下边坡参数（坡高、坡率）与边坡稳定性（稳定系数）的相关性，建立了煤矿区黄土边坡防治的上限方程；最后，根据工程实践和研究成果提出了边坡的防治建议。成果可对煤矿区的黄土边坡防治设计提供参考。

| Abstract: | Due to the uncertainly of loess slope failure (failure probability) and the special situation of slope in coal mining area, the stability of loess slope is often ignored and all of these reasons give rise to the slope accident occasionally. In order to explore the inherent mechanism of nature risk in slope, 40 loess slopes in coal mining area were studied by two-parameter statistical analysis. Firstly, slopes were divided into four stratum structure models according to the combined characteristics of geotechnical structure; Secondly, the slope parameters (slope height, slope ratio) and slope stability (stability factor) in various structural models were analyzed by establishing a limit equation about natural loess slope control in coal mining area; Finally, based on engineering practice and research results, control measures were put forward, which can provide reference for the design of prevention and control of loess slope in coal mining area. |
