Paper Abstract

Authors of this article focused on the analysis of the use of distributed fiber-optic technology for security monitoring of structural loads of road and motorway tunnels. Authors focused on measurements of deformation utilizing Brillouin Time Domain Reflectometry (BOTDR). The principle is based on the measurement of the stimulated Brillouin scattering. The article describes the load of tunnel based on the real measurements made during the construction of the motorway tunnel in the Slovakia Republic in a time horizon of several months. Experiments were carried out with standard optical telecommunication cable with water-absorbing aramid yarns and jacketing of diameter 4.2 mm. The outcome of this article is an introductory analysis the use of fiber-optic technology for security monitoring of structural loads for road and motorway tunnels.
