摘要： 针对岩爆评判模型中指标权重难以确定问题,提出一种“AHP+熵权法”组合赋权方法,引入Lagrange函数和欧氏距离函数,保证了主、客观权重与其差异程度相一致,最终获得理想的综合权重;基于逼近理想解排序法(technique for order preference by similarity to an ideal solution, TOPSIS)的基本理论建立CW(combined weights)-TOPSIS综合评判模型并预测岩爆等级。实例应用结果表明,CW-TOPSIS岩爆评判模型的预测结果与实际相吻合,进一步验证了该模型的有效性及实用性,从系统评价、多因素指标角度为岩爆预测提供了一种切实可行的途径。

Abstract: To solve the problem that the index weight is difficult to be determined in rockburst disaster assessment model, a combination weighting method of “AHP+entropy weight method” was proposed. The optimization comprehensive weight was established by introducing the Lagrange and Euclidean distance function, ensuring the consistency between the subjective, objective weight and the preference coefficient. Based on the basic theory of TOPSIS, a comprehensive evaluation model of CW-TOPSIS was established and applied to predict rockburst grade. The results of a case study showed that CW-TOPSIS rockburst evaluation model were consistent with the insitu actual conditions which further verified the validity and practicability of the model. The proposed method provided a feasible way for the rockburst prediction from the angle of system evaluation model and gulti-factors indexes.

Key words: CW-TOPSIS evaluation model, Lagrange function, rockburst, combination weighting
