摘要
针对岩体质量等级判定的不确定性,文章提出了熵权-联系云评价模型。首先采用熵权法确定各指标权重,基于联系云模型计算实测数据对应于各级别的确定度,然后根据最大隶属度原则判定岩体质量级别。实例应用及与其他方法评价结果的对比分析表明,熵权-联系云模型应用于实际工程岩体质量评价是有效可行的,且更加客观准确,可为露天矿工程岩体质量的评价提供参考。
Considering the uncertainty of rock mass quality evaluation, the entropy weights-connection cloud model was discussed. Firstly, the entropy method was adopted to determine the weight of each index, and the certainty degree of measured samples to the classification grade was calculated by means of connection cloud model. Then the quality level of rock mass was specified according to the principle of maximum membership degree. The evaluation results and the comparison with other methods indicate that the entropy weights-connection cloud model is effective and feasible for the rock mass quality evaluation in practical engineering and is more accurate and objective, which provides reference for the evaluation of rock mass of open-pit mine.
