南水北调东干渠输水隧洞监测技术

Monitoring Technology of East Main Canal Water Conveyance Tunnel of South-to-North Water Transfer

以南水北调东干渠输水隧洞盾构法施工监控测量为例,系统设计监测点位的监测内容、布设方式、监测方法和数据处理等检测环节,严格把控隧洞墙体位移及变形、支撑轴力、水位监测等监控测量各项指标,保证了输水隧洞的顺利完工。通过介绍隧道监控测量的方法,阐述了监控测量对指导施工的意义。

Faking the monitoring measurement of shield construction of east main canal water conveyance tunnel of the South-to-North water transfer as an example, this paper systematically designs the detecting units such as the monitoring content, layout mode, method and data processing, and completely controls all the indexes of monitoring measurements such as the wall displacement and deformation, supporting axial force and water level monitoring to ensure the completion of the water conveyance tunnel. Through the introduction of the tunnel monitoring measurement methods, the paper explains the significance of construction guidance of the monitoring measurement.
