DYNAMICALLY WEIGHTED GREY OPTIMIZATION MODEL FOR ROCKBURST RISK FORECASTING AND ITS APPLICATION TO WESTERN ROUTE OF SOUTH-NORTH WATER TRANSFER PROJECT
动态权重灰色归类模型在南水北调西线工程岩爆风险评估中的应用

Based on the principles of grey correlation analysis and fuzzy mode identity,a dynamically weighted grey optimization model for forecasting rockburst risk is established. In rockburst forecast,a new judging method is developed for composite judging index systems. This method overcomes the disadvantages of traditional methods and gives more reasonable results. The method was applied to prediction of rockburts in typical tunnel sections designed for the western route the South-North Water Transfer Project. The obtained results are compared with FEM analysis and show more accurate predictions .
