Abstract

Based on the construction project of Guangshan No.1 tunnel of Jinhong high-speed. The finite difference software is utilized to study the tunnel excavation with 3 different construction methods, the surrounding rock stress, displacement and plastic zone are analyzed. The influence of different construction methods on the surrounding rock and support of tunnel is determined, some suggestions and the optimization scheme have been proposed, which could also be recommended for similar future projects.
