Study on Enclosure Structure and Dewatering Plan for Open Cut Tunnel in the Connection Line between Line 1 and Line 3 of Chengdu Subway

Abstract:

On the basis of surrounding environment, including ground geological and hydrogeological condition of a connection line between line 1 and line 3 in Chengdu subway, open cut method is used to build the connection line. The whole line is divided into three sections, shotcrete and bolt support is adopted to maintain the stability of foundation pit by slope excavation, well rotary bored piles are used to support other foundation pit of the connection line. Meanwhile, the designed parameters of dewatering well points for the open cut tunnel are discussed and the anti-buoyancy ability of open cut tunnel is also analyzed in the paper. The purpose of this paper is to lead the design of open cut tunnels in Chengdu cities, including such similar subway tunnels in other cities in the world.
