This paper analyses the characteristics of the blasting-induced overbreak in some of the tunnels of the Brenner Base Tunnel (BBT) system, in order to evaluate its correlation with the main geometrical and technical parameters of the excavation as well as the geomechanical properties of the rock mass.
