Study on automatic convergence monitoring method during construction of long water delivery tunnel

针对长输水隧洞施工期收敛监测时效性差、对施工干扰较大、自动化水平较低等现状问题,文中提出利用激光测距仪和多功能采集仪搭建长输水隧洞的自动化收敛监测系统。通过对工程案例的输水施工期收敛变形监测数据进行分析,同时与全站仪收敛监测的结果进行对比分析,验证了该自动化收敛监测系统具有较高的精度和优势,可为其他相关工程提供借鉴和参考。

In view of the problems such as poor timeliness of convergence monitoring,great interference to construction and low level of automation during the construction period of long water conveyance tunnel,this paper proposes to build an automatic convergence monitoring system for long water conveyance tunnel by using laser rangefinder and multifunctional acquisition instrument.By analyzing the convergent deformation monitoring data of the engineering case during the construction period of water transmission,and comparing with the results of the total station convergence monitoring,it is verified that the automatic convergence monitoring system has higher accuracy and advantages,which can provide reference for other related projects.
