Bridge Monitoring Based on Beidou High-Precision Positioning: A Review

With the social development and economic progress, the safety monitoring of Bridges is becoming more and more important. The traditional bridge monitoring method has some problems, such as low monitoring precision, narrow monitoring range and high monitoring cost, which can not meet the actual demand. As a new bridge monitoring method, Beidou high precision positioning technology has the advantages of high precision, real-time and wide coverage, which provides a new possibility for bridge monitoring. In this paper, we summarize the principle and characteristics of Beidou high-precision positioning, analyze its application in bridge monitoring, and expound the bridge displacement, deformation and vibration monitoring based on Beidou. Finally, some suggestions on the application of Beidou high precision positioning in bridge monitoring are given, and the challenges and prospects are discussed.
