The present paper describes interesting geomechanical aspects from the conventional excavation on the Koralm Tunnel construction contract KAT3 under various conditions. The system behaviour and support concept are discussed and highlighted, both for the shallow tunnels in the vicinity of the western portal, situated in Neogene sediments with faults and those for sections in crystalline hard rock with the highest overburden of 1,200 m.
