Abstract: |
With a length of 32.9 km, the Koralm tunnel is the key structure on the route of the new 130 km Koralm railway between Graz and Klagenfurt (Austria). This paper defines the most important boundary conditions for dividing the sections and for selecting the methods of tunnelling (sequential or continuous). The focus of the article is mainly on section KAT 3, in which both tertiary sediments and crystalline rock sequences, including the Lavanttal fault zone, are excavated by sequential and continuous tunnelling. The considerations for this section also include the decision to excavate the sediments and the Lavanttal fault zone using a shield machine with earth pressure components. The criteria for defining the different operating modes are described. |
