The geological environment along the Sichuan-Tibet railway has the characteristics of plate splitting, frequent geological disasters, complex topography, large topography, cold climate, high cold and anoxia, etc. It is recognized by the world as one of the most difficult projects so far. Based on the construction of the tunnel entrance on the high and steep slope of the Sichuan-Tibet Railway, this paper conducts research on the construction of the tunnel construction, the reinforcement of the tunnel entrance and the protection of high and steep slopes. The integrated” tunnel entrance reinforcement system and the “carbon fiber lightweight active protection net” technology for slope protection are expected to provide a reference for the construction of the tunnel entrance of the Sichuan-Tibet railway high and steep slope.
