ABSTRACT
The excavation of the Brenner Base Tunnel requires solutions to multiple challenges. This article explains the methods used to excavate the stretch of the exploratory tunnel running through the Periadriatic Seam, where the Eurasian and Adriatic tectonic plates collide. During excavation, constant monitoring of convergence and tensions within the installed lining and ongoing adjustment of the cavity consolidation measures were of fundamental importance. This allowed us to create a stable balance between the highly tectonised rock mass and the in-stalled lining.
