| Abstract: | The characteristics and principle of FBG sensors are introduced briefly. After having used FBG sensors in the structural test of concrete segments of .subway tunnel in Shanghai, the strain of FBG sensors is compared with that of the strain gauges under multi-stage loading of testing machine, which are stuck to the same places of the surface of concrete segments, the result shows that the data obtained from FBG sensors tally with those from strain gauges. This provides a scientific basis for the research and application of the health-monitoring system of subway tunnel based on the FBG technology. |
