Implementation of structural health monitoring into life cycle management of tunnels: Case study Tunnel Brajdica

This paper presents a case study focused on the Brajdica railway tunnel, which carries the Zagreb-Rijeka railway line into the multi-modal port of Rijeka in Croatia and thus represents a critical node on the TEN-T network. The tunnel is undergoing a major reconstruction project, during which an extensive embedded monitoring system is being installed. The monitoring system includes a large range of equipment including inclinometers, extensometers, micrometers and survey markers which will be supplemented with periodical scanning of the tunnel interior using laser scanners. Measurement profiles will be set along the tunnel bore and the data collected will be used for validation of the geological and structural model and allow updating to be performed in real-time. Finally the performance model will be used for the development of the life cycle management scenarios, which will be used for the optimization of maintenance planning and identification of short and long-term risks. This work is a part of H2020 SAFE-10-T project.
