山西省中部引黄工程施工测量监测原理及方法

The Construction Measuring Principle and Method for Monitoring of Middle Yellow River Diversion Project in Shanxi Province

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 middle diversion project of Yellow River in Shanxi Province includes the water taking project ,main line, east line,west line the other water conveyance project of each water supply branch .The total length 384.5 km,and most of work is in tunnel ,which is a long-distance tunnel project .In order to make sure that the project can be finished smoothly ,it is necessary to monitor the project accurately and timely ,including the survey of control points and tunnel axis .In this paper,we provide a specific monitoring method and evaluation criterion for the project ,including the way of the repetition measurement of construction control points and critical design points of the tunnel ,and the evaluation method for workers who participate the project ,providing the management measures to make sure the successful completion of the tunnel .
