| Abstract: | In the construction of mountain highway tunnel, it is important to improve the construction technology to handle ground,chose excavation and entrance program in the condition of shallow buring,unsymmetrical load and soft surrounding,which is critical to the success of tunnel construction.Taking Zhangjiashan tunnels as an example which portal was shallow buried and unsymmetrical loaded,this paper analyses the surface grouting method and partial excavation method of the steel arch embedded in unilateral pre-cutting groove.The results show that the measures is effective in rock relaxation controll. |
