山西省中部引黄工程包括取水工程、总干线、东干线、西干线以及各供水支线输水工程。大部分工程为隧洞工程,线路总长384.5km,属于长距离隧洞工程。为了保证隧洞能够正确贯通,有必要对施工过程进行及时、准确的监测,包括控制点及隧洞轴线监测。针对该工程本文提出了具体的监测方法和评价标准,利用精密全站仪对施工控制点、隧洞设计关键坐标进行复测,对工程建设参与者的施工测量工作进行监控、监督和评价,并提出相应的管理措施,确保隧洞工程能够顺利贯通。
The Yellow River Diversion Project in central Shanxi Province includes the water intake project, the main trunk line, the East Main Line, the West Main Line and the water supply branch water diversion works. Most of the projects are tunnel projects, with a total length of 384.5km and belonging to long-distance tunnel projects. In order to ensure that tunnels can penetrate correctly, it is necessary to carry out timely and accurate monitoring of the construction process, including control points and tunnel axis monitoring. In view of the project, this paper presents a specific monitoring methods and evaluation criteria, the use of precision total station control points for the construction, the key coordinates of the tunnel design retest, construction project participants on the construction monitoring work, monitoring and evaluation, and put forward Corresponding management measures to ensure that the tunnel works smoothly.
