WANG Chang, NI Jia-sheng, LIU Xiao-hui, et al. Design and application of fiber inclinometer in dam slope monitoring[J]. 2013, 32(8): 114-116. DOI: 10.13873/j.1000-97872013.08.006.
Fiber Bragg grating is used to design a fiber inclinometer for remote and online monitoring on dam slope.Sensing principle
mechanical structure
installation of sensing unit and so on are described in detail.Precision of the sensor reaches 0.15°
and quantity of wavelength division multiplexing sensors of the system reaches 20.The technology is applied in several tailings reservoir’s dam safety monitoring.
