| 摘 要： | 在现场调研与文献分析的基础上，提出了排土场滑坡灾害预警指标体系。基于物元理论和关联函数，构建了露天矿山排土场滑坡灾害可拓预警模型。采用基于测度改进的层次分析法客观地确定评价指标权重，较好地消除了人为因素带来的偏差；以综合关联度作为评价准则进行滑坡危险性等级判定，进而对排土场滑坡灾害进行预警。利用该模型对某铁矿排土场的滑坡危险性进行预警评价，得到了与实际情况吻合的警情，并针对存在的问题提出了相应的改进措施

| Abstract: | Based on the on-site survey and literature analysis, an index system of landslide early-warning for open- pit dump was established. Based on matter-element theory and dependent function, a landslide early-warning model for open-pit dump based on extension theory was constructed. The evaluation criterion weight was ascertained with the method of improved analytic hierarchy process based on measure, which can reduce the deviation caused by ar- tificial influence. The comprehensive dependent degree was taken as the evaluation criteria to judge landslide risk grade, then landslide early-warning analysis was applied on open-pit dump. The early-warning model was applied on certain iron mine dump, and the results showed that this model has high accuracy, and the improving measure- ments were put forward in accordance with its problems. As a result, this method is scientific and rational, and thus worth popularizing and applying in coalmines. |
