摘要
以深中通道沉管隧道为例,针对沉管隧道最终接头横向贯通精度极高的要求,充分利用施工现场地形条件和隧道内部空间结构,对隧道洞内外平面控制网进行优化设计和横向贯通误差模拟计算,在左、右行车道和中廊道分别布设一套导线网,并相互连接,形成隧道多线形联合锁网贯通测量方法,实现了沉管隧道最终接头的精准合龙贯通.
Abstract
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.
