Distributed fiber optic sensors for tunnel monitoring: A state-of-the-art review
Delft University of Technology · Nanjing University · +1 more institution
Abstract
Distributed fiber optic sensors (DFOSs) possess the capability to measure strain and temperature variations over long distances, demonstrating outstanding potential for monitoring underground infrastructure. This study presents a state-of-the-art review of the DFOS applications for monitoring and assessing the deformation behavior of typical tunnel infrastructure, including bored tunnels, conventional tunnels, as well as immersed and cut-and-cover tunnels. DFOS systems based on Brillouin and Rayleigh scattering principles are both considered. When implementing DFOS monitoring, the fiber optic cable can be primarily installed along transverse and longitudinal directions to (1) measure distributed strains by…
