摘　　要：综合CW-GT法和TODIM法得到新组合预测模型,用于对岩爆倾向性进行预测。从应力、岩性与围岩方面选取了影响岩爆的8个主要评价指标,构建岩爆等级综合指标预测体系,再通过CW-GT法确定各评价指标的合理组合权重,进而结合TODIM法分别计算得到每个岩爆等级的总体感知优越度,从而预测得到相应岩爆等级。判断结果与AHP-TOPSIS和AHP-FUZZY综合评判模型的结果相吻合,实践表明:该模型适用于岩爆等级的预测,且预测的计算过程简单、清晰,为岩爆等级的预测问题提供了一条新的途径。In order to predict the rockburst tendency, the new combination prediction model on the basis of CW-GT and TODIM method was established. Eight main indexes influencing rockburst were chosen from stress, lithology and rock aspects, and the comprehensive index prediction system of rockburst grade was established. The reasonable combination weight of evaluation indexes were calculated according to the CW-GT, and then the overall perceived superiority degree of each rockburst grade was respectively calculated with the basic method of TODIM, thus the corresponding rockburst grade can be predicted. The prediction results are consistent with the results of AHP-TOPSIS and AHP-FUZZY comprehensive decision model. The practice shows that this model is suitable for the prediction of rockburst grade and the calculation process of pre- diction is simple and clear. It provides a new way for prediction of rockburst grade.
