MethodApplication of Distributed Optical Fiber Brillouin Sensing in Slope Monitoring

Distributed optical fiber Brillouin sensing technology can measure long distance strain and temperature distribution, and has natural advantages in long distance and wide range monitoring projects. Based on the dynamic monitoring project of the slope in the A pumped storage power station a distributed optical fiber monitoring technology scheme based on distributed optical fiber Brillouin sensing technology has been determined. The construction method of embedding optical fiber in engineering has been expounded. The test data show that the data of the distributed monitoring system is stable and meets the monitoring requirements of large range and high precision. It is suitable for the long time dynamic monitoring of the slope.
