| Abstract: | As influenced by tunnel opening interchange and overpass,the front slope of the tunnel opening is relatively high,therefore the stability of tunnel front slope is directly influencing safety of entering tunnel and in-tunnel driving.This paper introduces reason of deformation of high front slope at exist of Langtangshan tunnel during construction,it analyzes stability of the front slope and adopted reinforcement solution. |

| Keywords: | tunnel Stability of front slope anchor cable reinforcement residual down sliding force |
