摘要
为了对露天矿山边坡稳定性进行可靠分析,从采矿地质、水文特征和工程施工3个层面选取14项评价指标建立稳定性评价体系,并基于博弈论构建露天矿边坡岩体稳定性综合评价云模型。以云南某露天矿边坡为工程案例,通过数学计算并评估其稳定性等级。结果表明:优化后的层次分析法能够明显改善主观权重的计算精度;选取的模型评价指标符合工程实际需要,且具有良好的独立性与代表性;博弈论可以较好地求出评价指标的综合权重,云模型能够逐级分析出各层指标与稳定性等级的相关程度,并根据最大隶属度原则,得出露天矿边坡岩体稳定性等级。
To analyze the stability of open-pit mine slope reliably,14 evaluation indexes are selected from three aspects of mining geology,hydrological characteristics,and engineering construction to establish a stability evaluation system,and a comprehensive evaluation cloud model of open-pit mine slope rock mass stability is constructed based on game theory.Taking an open-pit mine slope in Yunnan as an engineering case,its stability grade is evaluated by mathematical calculation.The results show that the optimized analytic hierarchy process can significantly improve the calculation accuracy of subjective weight.The selected model evaluation index meets the actual needs of the project,and has good independence and representativeness;the game theory can better calculate the comprehensive weight of the evaluation index.The cloud model can analyze the correlation degree between the indexes of each layer and the stability grade step by step.According to the principle of maximum membership degree,the stability grade of open-pit slope rock mass is obtained.
