Structural health monitoring with distributed optical fiber sensors of tunnel lining affected by nearby construction activity
This paper addresses the implementation of a Distributed Optical Fiber Sensor system (DOFS) to the TMB L-9 metro tunnel in Barcelona for Structural Health Monitoring (SHM) purposes as the former could potentially be affected by the construction of a nearby residential building.

| Sumario: | This paper addresses the implementation of a Distributed Optical Fiber Sensor system (DOFS) to the TMB L-9 metro tunnel in Barcelona for Structural Health Monitoring (SHM) purposes as the former could potentially be affected by the construction of a nearby residential building. With the aim of assessing the performance of this newly developed monitoring technology, an in-depth analysis on the collected strain readings is performed from which innovative data post-processing techniques are developed. Finally, the reliability of the installed DOFSs system is studied by means of a comparison with a theoretical model of the site’s structural conditions. |
