Experimental Research of Distributed Optical Fiber Sensor Monitors the Embankment Hidden Hazard
Distributed optical fiber sensor as the basis for temperature difference and strain identification, it has some advantages on deformation monitoring and seepage monitoring of the dams relying on long distance, continuous monitoring ability, distributed performance, strong anti-interference ability and other characteristics that traditional sensors do not have advantages. Taking layout of layered installation for example, this paper studies the relationship between laying bending radius and the strain sensing characteristics of the optical fiber sensor. The test of through the indoor simulated experiment and the outdoor dam model monitoring shows that the distributed optical fiber sensor for dam danger monitoring has good effect and promising applications. The dam model provides experimental platform to further study early warning criterion of dam hidden disaster.
