QIU Dao-Hong,CHEN Jian-Ping,ZHANG Bing-He,XIAO Yun-Hua(Construction Engineering College,Jilin University,Changchun 130026,China)  
Being a kind of familiar geological hazard in deep and over-length highway tunnel,rockburst greatly threaten the safety of construction personnel and equipment.On the basis of analyzing the factors affecting rockburst and in combination with the character of the tunneling engineering,this paper has put forward the matter-element model forecasting rockburst and has evaluated the gradation of rockburst through extensions.Finally,based on the practical situation,this paper advances the prevention measure.The practical example demonstrates that the evaluating result of the model is reliable,so this method has a vast prospect in predicting rockburst.
