Monitoring system for cable force state of steeve arch in cold area

The cable force state of steeve arch is one of the key factors which determine the safety of operation of the steeve arch. In order to master the cable force state of steeve arch, a cable force monitoring system has been established, and in this monitoring system, the cable force state can be real-time monitored by using random vabration response of suspenders under ambient excitation. In order to improve the data transmission efficiency, firstly, in the monitoring system, the collected massive data can be discriminated and screened, and then only the screened effective data will be transferred. The single cable force and the full bridge cable force with short length can be analyzed exactly. And the cable force monitoring system has high immune function in the influence of ambient temperature difference on cable force. By the analogue debugging of this monitoring system, the effectiveness and reliability of this monitoring system in the cable force state monitoring application of steeve arch in cold area are verified.
