| Abstract: | The structural on-line monitoring system of long-span bridge aimed to detect damage,analyze reliability and reduce cost of maintenance is a hot spot in recent years.In this paper,the insufficiency of manual detection is analyzed.Based on applicability and cost-benefit analysis,how to select the items of the monitoring system and instruments is discussed with the example of the structural on-line monitoring system for Dongting Lake Bridge,as well as the system's structure and the network topology and the communication technology.Further more,in order to enhance the damage detection and reliability analysis,a remote monitoring and diagnoses system based on Internet is presented. |
| Keywords: | bridge structural condition on-line monitoring system |
