Understanding spatial and temporal evolution of progressive excavation damage zone in granitic rocks – development of a novel mine-by and laboratory experimental framework at the BedrettoLab

Abstract. The brittle damage around tunnels in the form of spalling is common in massive crystalline rocks subjected to high in-situ stresses. Understanding the short-term development and long-term evolution of the Excavation Damage Zone (EDZ) is particularly important for deep g...
