中文摘要: 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;结合现场实测,相较于传统评价模型,基于博弈论综合评价云模型适用性较好,分析结果准确可靠,能够为类似采矿地质条件矿山边坡岩体稳定性分析提供一定的理论参考。
Abstract:In order to conduct a reliable analysis of the stability of open-pit mine slopes, 14 evaluation indicators were selected from three levels: mining geology, hydrological characteristics, and engineering construction to establish a stability evaluation system. Based on game theory, a comprehensive evaluation cloud model for the stability of open-pit mine slope rock masses was constructed. Taking an open-pit mine slope in Yunnan as an engineering case, the stability level was evaluated through mathematical calculation. The results show that the optimized Analytic Hierarchy Process can significantly improve the accuracy of subjective weight calculation; The selected model evaluation indicators meet the actual needs of the project and have good independence and representativeness; Game theory can effectively calculate the comprehensive weights of evaluation indicators, and cloud models can analyze the correlation between each layer of indicators and the stability level step by step. Based on the principle of maximum membership, the stability level of open-pit mine slope rock mass can be determined; Based on on-site measurements, compared to traditional evaluation models, the comprehensive evaluation cloud model based on game theory has better applicability, accurate and reliable analysis results, and can provide a certain theoretical reference for the stability analysis of slope rock masses in similar mine geological conditions.
