【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]:According to the weights of the index evaluation model of rock burst is difficult to determine the problem, put forward a "AHP+ entropy method" combination weighting method, introducing the Lagrange function and the Euclidean distance function, which is consistent with the main objective weight difference degree, the comprehensive weight for ideal; TOPSIS method based on technique (for order preference by similarity to an ideal solution, TOPSIS) of the basic theory of CW (combined weights) -TOPSIS comprehensive evaluation model and grade of rock burst prediction. The application shows that the prediction results of the CW-TOPSIS evaluation model of rock burst is consistent with the actual, further verify the validity and practicability of this model, the system of evaluation, multi factor index angle of rock burst prediction provides a feasible way.

【正文快照】： 0引言岩爆是深埋隧道施工过程中常见的动力破坏现象,具有一定的突发性、随机性和不可预测性[1-3]。随着对岩爆研究的深入,对岩爆影响因素的考虑愈加全面,也越倾向于采用平行多指标综合评价法来对岩爆灾害进行预测研究,系统评价模型由此而生,代表性的有模糊数学[4]、突变理论[5
