Abstract:

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 monitoring 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.
