Fiber Bragg Grating (FBG) sensor systems are widely used to monitor mechanical parameters for structural health monitoring (SHM) of civil engineering structures. Among many applications, FBG technology allows the development of weighing pads with a fully passive optical working principle, with no need for electrical power at the measuring point. In this contribution, a technical solution for monitoring the navigability of the “Po” river, proposed in the framework of the European project CRISTAL (Climate resilient and environmentally sustainable transport infrastructure, with a focus on inland waterways) is investigated. The preliminary laboratory test to assess the feasibility of a procedure based on FBG technology to monitor sand accumulation on the riverbed is exposed, by using a weighing pad instrumented with FBGs. Indeed, its design and prototype realization are under development in the ENEA FOS (Fiber Optic Sensor) laboratory.

Abstract
Fiber Bragg Grating (FBG) sensor systems are widely used to monitor mechanical parameters for structural health monitoring (SHM) of civil engineering structures. Among many applications, FBG technology allows the development of weighing pads with a fully passive optical working principle, with no need for electrical power at the measuring point. In this contribution, a technical solution for monitoring the navigability of the “Po” river, proposed in the framework of the European project CRISTAL (Climate resilient and environmentally sustainable transport infrastructure, with a focus on inland waterways) is investigated. The preliminary laboratory test to assess the feasibility of a procedure based on FBG technology to monitor sand accumulation on the riverbed is exposed, by using a weighing pad instrumented with FBGs. Indeed, its design and prototype realization are under development in the ENEA FOS (Fiber Optic Sensor) laboratory.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
