Research on Bridge Structure Health Monitoring Based on GPS

Bridges play a more and more important role in human society. For this reason, the structural safety of the bridge needs to be highly valued. The traditional structural health monitoring technology can continuously and regularly measure the key structural and environmental parameters of the bridge, so as to avoid casualties. However, with the increasing complexity of bridge design structure, more comprehensive information needs to be collected and measured. Structure Health Monitoring (SHM) technology combined with Global Positioning System (GPS) came into being. This paper briefly expounds the principle of GPS positioning, and also introduces some cases of using this technology. The problem of excessive observation noise and the effect of using Chinese Beidou navigation is also discussed. At the same time, the paper also points out the problem of excessive observation noise and that the observation accuracy and radio anti interference ability should be improved in the future
