摘　　要：露天矿边坡环境复杂,从影响因素角度难以准确建立其与边坡风险的联系。为此基于能直接反映边坡安全程度的实时监测来建立露天矿边坡的风险评估方法,根据边坡实际的监测项目建立了一套完整的边坡风险评价体系,该体系以监测项目的单项预警值为参考,通过划分风险等级区间与相应的概率相匹配,并结合权重以及层次分析法来获取各监测项以及边坡综合风险概率。The environment of opencast mine is complicated and many factors influence the risk of the slope. But the connection between the factors and risk is hard to be precisely established. So a new method based on the real- time monitoring which can reflect the safety level of the slope is developed. In this method,a new evaluation system which consists of the specific monitoring items is established. The system refers to alarm value of each item and partitions different intervals to match the corresponding probabilities,and the probability of each monitoring item and the comprehensive probability of the slope can be obtained by combining with weight values and AHP method.
