Abstract: In the paper, the predicting of rockburst in the Xuefeng mountain express highway tunnel has been given by using of two effective measures of forecasting -geology complex forecast method and σ_θ/Rb judging method, through study of engineering geology conditions and geostress field of the tunnel and rock mechanics experiment. The result is that the probability of high tensity rockburst in the tunnel is non-existent and the probability of low grade and moderate tensity rockburst in the tunnel is existent. It has supplied design basis for the tunnel.
