The surrounding rock in Hongtiguan tunnel is mainly hard rock, which is an extra long and deep buried tunnel. The geological structure around the tunnel is developed very well, engineering geological conditions are complicated and there is great possibility for rockburst. Through the analysis on influencing factors of rockburst, hydrofracturing method, Taozhenyu method, shear stress criterion were used to test ground stress, the results show that there are occurrance possibilities of weak-moderate rockbursts in this tunnel.
