| Abstract: | Comparing with the strain sensors based on traditional testing technology, fiber grating strain sensors have prominent advantages of high precision, simple and convenient testing, good long-term reliability, as well as powerful anti-jamming capability. This paper is mainly concerned with the structural characteristics and research process of fiber grating strain sensors, successful applications of strain sensors in the bowstring arch bridge, particularly the tie bar cable replacement. The results indicate that fiber grating strain sensors are able to monitor the tension status about reinforced concrete bowstring arch bridge effectively. |
