摘要: 目前地铁隧道结构沉降主要采用水准仪进行人工测量。该监测方法不仅作业效率低、耗费较多的人力物力,并且无法实现全天候监测。针对传统人工监测无法满足地铁运营期间的实时监测需求的问题,本文引入静力水准自动测量技术,通过在地铁隧道道床布设静力水准仪,在远程采集端实时获取监测点数据,实现隧道结构保护区在施工时全程监测,为施工期隧道结构安全提供保障。最后结合实际工程应用案例对工程中的监测结果进行分析。结果表明,该技术实现了地铁隧道自动化水准测量,为地铁运营安全提供技术支撑。

Abstract: At present, the settlement of subway tunnel structure is mainly measured manually by leveling instrument.This monitoring method not only has low work efficiency, consumes a lot of manpower and material resources, but also can not achieve all-weather monitoring. Traditional manual monitoring can not meet the real-time monitoring requirements during subway operation.To solve this problem, this paper introduces the automatic static leveling measurement technology, through the deployment of static leveling gauges on the subway tunnel track bed, real-time monitoring point data is obtained from the remote control terminal, realizing the whole process monitoring during the construction of the tunnel structure protection area, and provides guarantee for the safety of the tunnel structure during the construction period. This article analyzes the actual engineering application cases and the monitoring results in the project. The results show that this technology realizes the automatic leveling of subway tunnels and provides technical support for the safety of subway operations.
