Abstract 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.

受附近施工活动影响的隧道衬砌分布式光纤传感器的结构健康监测

摘要 本文讨论了分布式光纤传感器系统 (DOFS) 在巴塞罗那 TMB L-9 地铁隧道中的实施，用于结构健康监测 (SHM)，因为前者可能会受到附近住宅建筑施工的影响。为了评估这种新开发的监测技术的性能，对收集的应变读数进行了深入分析，从中开发了创新的数据后处理技术。最后，通过与现场结构条件的理论模型进行比较，研究了已安装 DOFS 系统的可靠性。
