| Abstract: | Tiandong Tunnel is a large section road tunnel,its geological conditions in the exit section with weak rock is very complex,where groundwater is abundant.So we took bench method with the help of grouting,water sealing and reinforcement measures in the construction.These measures brought excellent excavation effect,not only quickened the construction pace,but also raised the construction quality,protected surrounding mountain and environment. |
