Design and application of multi-linear interlocking network penetration measurement method for installation of super-large steel shell concrete immersed tube
Taking the immersed tube tunnel of the Shenzhen-Zhongshan Link as an example,in view of the extremely high requirement of transverse penetration precision of the final joint of the immersed tube tunnel,the topographic conditions of the construction site and the internal spatial structure of the tunnel are fully utilized,the plane control network inside and outside the tunnel is optimized and the transverse penetration error is simulated and calculated,a set of wire networks is arranged in the left and right lane and the middle corridor respectively,and connected to each other to form a multi-linear interlocking network penetration measurement method,achieving precise closure and penetration of the final joint of the immersed tube tunnel.
