摘要
为准确评价露天矿边坡的稳定性,提出了模糊层次分析法和组合熵权法相结合的综合评价方法。首先根据经验建立以地形地貌、岩土性质、水的影响、震动影响及其他影响为一级指标的评判因素集,再运用模糊层次分析法求解各因素的权重,然后运用组合熵权法对因素集样本数据进行关联性分析,并进一步修正权重系数,最终得到边坡稳定性的综合评价结果。该方法考虑了实际数据分布,修正了权值不均衡问题,评价结果优于单一层次分析法,为露天矿山的实际生产和管理提供了有益参考。
Aimed at an accurate evaluation of the slope stability of open-pit mine,this paper introduces a comprehensive evaluation model consisting of fuzzy analytic hierarchy process and combination entropy-weight method.The model starts with developing evaluation factors set of the first level,including the topography,soil properties,water effects,shock effects and other effects,according to the experience,proceeds to calculate every factors＇weight using fuzzy analytic hierarchy process,and ends with analyzing the relatedness of sample data using the combination entropy-weight method,so as to determine the results of slope stability evaluation by further amending the weight coefficient.Allowing for the actual data distribution,the method,overcoming weight＇s imbalance,gives the evaluation result better than does the single analytic hierarchy process.This evaluation model can provide useful reference for the actual mine production and management.
