Paper Abstract

The proposed desensitized encapsulation structure solved the problem that more than 5500με test range for FBG sensor. The single steel wire with proposed FBG sensor tension test in laboratory before and after fatigue experiment showed the rationality and reliability of sensor structure. A scheme using desensitized encapsulation FBG sensor to fabricate smart cable which was compatible with production process of parallel steel wires cable was designed. The specimen cable tension test verified sensors high survival rate of the design scheme and good long-term precision after fatigue experiment. Also the actual application of smart cable was tested by one bridge during the construction and operation stage.
