Numerous tunnel rings are continuously monitored with Sacertis' Smart Segment solution for the time-varying evaluation of the tensile-deformation response of the lining. The sensors were embedded in the prefabricated tunnel segments during casting and connected during TBM installation.
Each ring is equipped with bi-axial MEMS inclinometers and patented tension-deformation sensors, a data collection and pre-processing gateway, and a cloud-based architecture for data transfer and subsequent post-processing analyses. The diagnostics are supported by non-linear FE models developed for the evaluation of the expected behavior.
A great project for a great tunnel.
