This paper reports about a tunnel monitoring approach based on distributed fibre optic sensing (DFOS), which allows strain and temperature measurements along the installed sensor line inside shotcrete tunnel linings with a spatial resolution of 0. Optimal distributed detection for leak detection and third-party interference monitoring by DTS and DAS with fiber optic cables and without influence of the hydraulic conditions of the pipeline, offering long measurement range with virtually no maintenance for decades. Accordingly, the health status of the tunnel is dynamically grasped, which is of great significance to ensure the. Today, modern monitoring systems allow reliable condition monitoring of tunnels using optical sensor technology, based on fiber Bragg technology. Tunnels are at the core of our infrastructure.
