Tunnel and underground engineering is a promising science to solve the traffic and industrial problems in our country. Taking the shield section from Yingrenshi Station to Luozu Station in the fourth work area of Shenzhen metro line 13 as an example, this paper expounds the application of the conductor layout method in the long section shield tunnel, which adopts the addition of a common edge between the main conductor and the auxiliary conductor to form a closed loop, compares and analyzes with the gyro directional data, and measures the penetration error after the tunnel is penetrated, so as to provide help for the layout of the long section shield tunnel control survey control network.展开更多
