基于博弈论综合赋权-物元可拓理论的岩爆倾向性预测
Prediction of rockburst tendency based on game theory comprehensive weighted matter-element extension theory
摘要
Abstract
In the study of rock burst tendency prediction,the randomness of the weighting results of a single weigh-ting method is high,and the calculation of weight combination is not scientific and reasonable enough,resulting in low accuracy of rock burst prediction.Four methods,including multiplication combination weighting,rough set theory(RS),CRITIC method,and game theory comprehensive weighting method,were used to determine the weights.The matter element extension theory was introduced,and the rock burst level was determined based on the maximum cor-relation degree criterion;Selecting stress coefficient,strength brittleness coefficient,elastic energy index,and sur-rounding rock integrity coefficient as evaluation indicators,analyzing 20 typical rock burst data at home and abroad as samples,comparing the accuracy of rock burst level prediction results obtained by four weighting methods,the results show that the rock burst prediction model based on game theory comprehensive weighting extension theory has a pre-diction accuracy of 95%,which is higher than the prediction accuracy of the other three weighting methods.The mod-el was applied to predict rock burst in the diversion tunnel of Jinping second-level hydropower station,and the results obtained were consistent with the on-site results,further verifying the reliability of the model in this paper.关键词
