摘要
以工程实例为依托,介绍以徕卡TCA1800型全站仪为基础组成的自动化变形监测系统,在广州市天誉四期基坑相邻地铁隧道结构监测项目中的应用,利用自动化监测技术,在深基坑开挖施工过程中对毗邻运营地铁隧道的结构变形情况进行监测,通过对各变形监测点的变形量与预警值的比较和综合分析,提出预警预测,确保在项目施工期间地铁隧道的结构安全和正常使用。实际应用证明,该自动化变形监测系统稳定可靠,达到监测的目的,可广泛应用于运营地铁隧道结构安全的监测预警工作。
Taking an engineering example,this paper introduces the automatic deformation monitoring system based on the Leica TCA1800 model total station to monitor adjacent operation subway tunnel deformation in Tianyu four stage foundation pit excavation project in Guangzhou city.This paper uses automatic monitoring technology to monitor the deformation of adjacent operational subway tunnel,in the process of deep foundation pit excavation.Based on the comparison and comprehensive analysis of the deformation and the warning value of the monitoring point,it provides early warning forecast to ensure the structural safety and normal use during the construction of subway tunnel.The practical application proves that the automatic deformation monitoring system is stable and reliable,achieves the purpose of monitoring,and can be widely used in the monitoring and early warning of the safety of subway tunnel structure.
