Prediction of Rockburst Intensity Level in Tunnels Based on Game Theory-Improved Unascertained Measure Theory
提出一种岩爆烈度的预测模型,分别采用AHP层次分析法、熵权法确定主观、客观权重,通过博弈论的思想得到综合权重;采用闵可夫斯基距离公式改进未确知测度理论,从而优化属性识别模式;分析岩爆的产生机理和关键影响因素,选取岩石力学性质、围岩及应力等 5项评价指标;通过 20组工程岩爆数据对提出模型进行验证,改进后的评价模型准确率高达95%.
A prediction model of rock burst intensity is proposed.The subjective and objective weights are determined by AHP analytic hierarchy process and entropy weight method,respectively,and the comprehensive weights are obtained by game theory.The Minkowski distance formula is used to improve the unascertained measure theory,so as to optimize the attribute recognition model.The generating mechanism and key influencing factors of rock burst are analyzed,and five evaluation indexes such as rock mechanical properties,surrounding rock and stress are selected.The proposed model is verified by 20 sets of engineering rock burst data,and the accuracy of the improved evaluation model is as high as 95%.
