Paper Abstract

The long span highway-railway cable-stayed bridge bears huge permanent load and heavy moving load. The structural internal force is the key for bridge safety operation. This paper introduces the fiber Bragg grating (FBG) strain sensor, FBG force-testing ring and FBG acceleration sensor to monitor the pivotal parameters of dynamic strain, cable force and dynamic characteristics. The bridge health monitoring system based on the three FBG sensors has been applied in Tianxingzhou bridge. The FBG sensors were monitoring during bridge construction stage, load test and normal operation. The analysis based on engineering monitoring data indicates that the data of FBG sensors are stable and reliable.
