Abstract Based on the primitive gray GM(1,1) model, the water gush prediction in the No.6 inclined shaft of the Guanjiao tunnel is simulated by the model established and the equal mileage spacing sequence is analyzed. After examination, it is concluded that the prediction precision is high and that the model is practical for short-term prediction of water gush in tunnels.
