A review of DFOS sensors installation methods for curved surfaces in tunnels
A review of DFOS sensors installation methods for curved surfaces in tunnels
This paper reviews previous published articles on structural health monitoring (SHM) of tunnels using distributed fibre optic sensing (DFOS). The installation of DFOS sensors onto curved surfaces in tunnels, such as the transverse cross section of a tunnel, is a major challenge for the effectiveness of SHM of tunnels. The state-of-the-art DFOS sensors installation methods currently used for monitoring surface strains in tunnels are summarized, with emphasis on evaluating the applicability scenario of each method and their advantages and disadvantages.
