Experimental Research on Embankment Hidden Defects Monitoring Using Distributed Optical Fiber Sensor

Abstract:

Distributed optical fiber sensor for temperature and strain identification as the basis, the optical fiber sensor has advantages to monitor deformation and seepage in the embankment dam relying on its long distance and continuous monitoring ability. Taking layout of layered installation, the relationship between laying bending radius and the strain of the optical fiber sensor is studied. Indoor simulation test and local outdoor dam model test show that, the distributed optical fiber sensor for dam defect monitoring has good effect and application prospect. The embankment dam model provides experimental platform to further study early warning criterion of impending disaster in embankment dam.
