一套合格的隧道工程控制测量方案是保证隧道工程施工质量的前提,对满足隧道工程施工所必须的准确定位、实时监控、进程监控和工程的顺利贯通起到了决定性的作用。隧道控制测量的目的即是保证隧道在两个或两个以上开挖面的相向施工中,使其中的线形符合线路平面和纵断面的设计要求,并在满足限界要求的条件下、在允许的误差范围内,使两个相向施工的开挖面正确贯通。本文基于本人参与的郑西客运专线秦东隧道控制测量,通过对黄土隧道工程特点的阐述及通过导线的布设及测量等级的确定,测量方法,导线的检测及等几个方面介绍了黄土隧道的控制测量方案,进而分析了在黄土隧道控制测量中的注意事项及具体要求。
A set of qualified tunnel project control measurement scheme is the precondition to ensure the construction quality of the tunnel project. It plays a decisive role in the accurate positioning, real-time monitoring, process monitoring and smooth project construction necessary to meet the tunnel construction. The purpose of tunnel control measurement is to ensure that the tunnel in two or more excavation face opposite construction, so that the line shape line with the line plane and vertical section of the design requirements, and meet the requirements of the boundary conditions, Within the error range, the excavation surfaces of the two opposite constructions should be properly penetrated. Based on the measurement of Qindong Tunnel of Zheng-Xi Passenger Dedicated Line, this paper introduces the engineering characteristics of loess tunnel, the design of measuring and measuring methods, the testing method of wire, and the detection of loess tunnel Control the measurement scheme, and then analyze the considerations and specific requirements in the loess tunnel control measurement.
