Title:
Abstract:	The following article deals with the design of the inner lining of the Gotthard Base Tunnel and the determination of the design loads. The determination of the loads is based on the geological conditions encountered and takes into account the installed support measures and the deformation, occurring. The observational method also makes a considerable contribution. Together with the criteria stated above, it proved possible to find a definition of the hazard scenarios and the resulting rock pressure in order to optimise the design of the inner lining. Der folgende Beitrag behandelt die Dimensionierung der Innenschale des Gotthard Basistunnels und die Ermittlung der hierfür anzusetzenden Lasten. Die Lastenermittlung basiert auf der angetroffenen Geologie unter Berücksichtigung der eingebauten Sicherungsmittel und der eingetretenen Deformationen. Einen nicht unwesentlichen Beitrag dazu leistete die Beobachtungsmethode. Zusammen mit den vorgenannten Kriterien gelang es, eine Definition der Gefährdungsbilder und den damit gegebenen Gebirgsdrücken zu finden, um schließlich die Dimensionierung der Innenschale zu optimieren.
