Comprehensively Integrated Methods of Rockburst Prediction in Underground Engineering

LI Tianbin1,XIAO Xuepei1,2(1.State Key Labortory of Geohazard Prevention and Geoenvironment Protection,Chengdu University of Technology,Chengdu 610059,China;2.Sichuan Province Communication Department Highway Planning,Survey,Design and Research Institute,Chengdu 610041,China)  
In view of the low accuracy of rockburst prediction in underground engineering and the flaws of existing methods of prediction,an academic thought of comprehensively integrated prediction for rock burst is put forward in the paper.According to the thought,the rockburst prediction must combine the qualitative prediction with the quantitative forecast,the single factor prediction with the many factors forecast.Nonlinear scientific theory,which is effective in solution of complex problems,should be used to the comprehensively integrated prediction for rock burst.In this paper,the comprehensively integrated methods of rockburst prediction are recommended in detail,including comprehensive geologic analysis,stress-strength ratio method,AHP-FUZZY assessment and neural network method.These methods were used to forecast the rockburst of traffic tunnels in Jinping Ⅱ Hydropower Station on Yalong river in west China,obtaining a good results.
