A monitoring network to measure the cracks in a tunnel subject to shear deformation induced by landslide

This works describes the monitoring activity of a road tunnel that interferes with a large landslide provided for the Italian National Road Authority (ANAS). The monitoring network controls the cracks that formed on the tunnel lining due to the unremitting movements of the landslide. Scope of the monitoring campaign is to understand the dynamic of the process with respect to triggering factors such as rainfall, snow melt, and saturation of the rock mass. This is done in order to provide the Road Authority suggestion for effective structural mitigation works that would ensure the safety and durability of the road tunnel.
