摘要：

为确保北京地铁5号线崇文门站施工期间其上方既有地铁隧道的运营安全，采用远程自动监测系统对既有地铁结构的动态变化进行了实时监控。该监测系统由传感器子系统、数据采集与传输子系统和数据管理子系统构成，可以最大限度地降低监测与运营的相互影响。传感器子系统包括静力水准仪、梁式倾斜仪、位移计和测缝计，分别监测隧道沉降、道床沉降、两走行轨横向高差和水平间距以及结构变形缝的变化；数据采集与传输子系统将采集到的数据以有线方式传输至信息中心；信息中心的数据管理子系统对接收到的数据进行处理，并通过公共网络将监测信息及时反馈给相关单位。该系统在北京地铁5号线崇文门车站下穿环线地铁隧道施工期间对既有地铁结构的变形实施了有效监控，有关单位根据监测系统反映的异常情况及时调整了施工措施，取得了理想的控制效果，保证了施工期间既有地铁线路的安全运营。

Abstract:

In order to guarantee the operation safety of the metro above during the construction of Chongwenmen station in Beijing metro No.5, the remote monitoring system is used to measure the dynamic changes of existing metro structure. The monitoring system is composed of sensor subsystem, data acquisition and transmission subsystem, and data management subsystem, which can reduce the interaction between the monitoring and subway operation in maximum. The sensor subsystem consists of static force level gauge, beam inclinometer, displacement sensor and joint meter, which are used to monitor the settlements of existing tunnel and track bed, transverse height difference and horizontal space between two running rails and changes of the structure slots respectively. The data acquisition and transmission subsystem can transfer the collected data to the information center by wired medium. The data received will be treated by the management subsystem; and then fed back to related departments and companies by public network. The deformations of the existing metro structure are monitored effectively by the system during the undercrossing construction of newly-built metro station; and the control measures are adjusted in time according to the deformation data so as to make the existing metro runs safely.

Key words: metro station construction, existing metro tunnel, safe operation, remote monitoring system, real-time automatic monitoring
