选择岩体应力指数、脆性指数、完整性系数、以及弹性能量指数作为岩爆预测评判指标,以相似数定义相似权的方法,按一种客观性标准确定岩爆预测综合评价指标的权重,应用属性测度理论建立基于相似权的岩爆综合评价属性测度模型.针对一些岩爆试验数据进行分析,评价结果与试验情况基本一致,并且与模糊综合评判法的评判结果有较好的一致性,从而验证了属性测度模型应用于岩爆预测预报的可行性和有效性.由于属性识别理论能很好地解决某类问题具有多个模糊属性的综合评价,且置信度准则是根据评价集具有有序性这一特点而提出的,因而可使评价结果更为可靠;同时评价模型采用客观性权重,避免了权重确定中的主观性和随意性,保证了评价工作的客观性和准确性.
Rock mass stress index, brittleness index, completeness coefficient and elastic energy index are selected as the rock burst predictive index, and similarity weight is used to define the weight of comprehensive evaluation index of rock burst based on an objectivity criterion. Attribute measure theory to establish the rockburst comprehensive evaluation attribute measure model based on similarity weight.According to some rock burst test data, the evaluation results are basically the same with the experimental ones, and they are in good agreement with the fuzzy comprehensive evaluation method, The feasibility and effectiveness of the attribute measure model applied to rockburst prediction are verified.As the attribute identification theory can well solve the comprehensive evaluation of a certain kind of problem with multiple fuzzy attributes and the confidence criterion is based on the order of evaluation set Therefore, the evaluation result can be more reliable. At the same time, the evaluation model adopts the objective weight, which avoids the subjectivity and arbitrariness in the weight determination, and guarantees the objectivity and accuracy of the evaluation work.
