摘　　要：远程自动化监测系统由测试设备、数据自动采集器和应用终端组成,具有自动化、连续监测的优点。在北京地铁五号线崇文门站下穿既有环线地铁区间工程中,将静力水准、测缝计等组成远程自动化监测系统应用于既有线的结构及道床监测,通过施工期间的实时监测,快速反馈信息,指导施工,保障了新建车站的顺利通过和既有地铁环线的运营安全。The remote automatic monitoring system is composed of monitoring equipment, automatic data-collecting instruments and application terminal, which has such advantages as automatic and continuous monitoring. Chongwenmen station on line 5 of Beijing Metro crosses below the loop line of Beijing Metro. During the construction of Chongwenmen station, an automatic monitoring system, which comprises of hydrostatic levels and joint meters, is applied for the moni- toring of the tunnel structures and the roadbeds of the existing Metro line. By means of real-time monitoring made during construction, the monitoring results are quickly fed back to provide guidance for the construction. Therefore, the successful construction of Chongwenmen station and the safe operation of the loop Metro line are guaranteed.
