Monitoring system for previous convergence measurements in tunnel construction

Abstract

During excavation and operation of geotechnical projects such as tunnels, their deformation affects other infrastructure facilities. Therefore, continuous monitoring is required to minimize potential hazards. This task can be realized with the methods of DSTS - technology. Fiber optic sensor technology has progressed at a rapid pace over the last decade. Strain measurement with a distributed Brillouin scattering based sensor system provides excellent opportunity for geotechnical monitoring. Using this technology, it will be possible to create the wide metrological basis for an evidence-based risk assessment in geotechnology. This makes it possible, among other things, to optimize the construction process in such a way that a balance is created between improving safety and reducing costs.
