Title:
Abstract:	The construction of the first tube of the Tauern tunnels in the years 1970 to 1975 was a milestone in the development of the NATM and of modern tunnelling. Completely new methods were introduced and used successfully to overcome the strongly squeezing rock, which was the only possibility of mastering the large rock deformations and completing tunnelling within the planned deadline. The driving of the second tube of the Tauern tunnel between 2006 and 2008 has shown that the basics of the NATM are still valid. The considerably more favourable system behaviour does, however, show that the state of knowledge in design and construction has developed greatly. The major difference is the increase of productivity and this is made clear by comparing the production assets used. Der Bau der ersten RÃ¶hre des Tauerntunnels in den Jahren 1970 bis 1975 war ein Meilenstein in der Entwicklung der NÃ–T und des modernen Tunnelbaus. Zur BewÃ¤ltigung des bereichsweise stark druckhaften Gebirges wurden vÃ¶llig neue Methoden umgesetzt und erfolgreich angewendet, nur dadurch konnten die groÃŸen Gebirgsverformungen beherrscht werden und der Tunnelvortrieb in der vorgesehenen Zeit abgeschlossen werden. Der Vortrieb der zweiten RÃ¶hre des Tauerntunnels von 2006 bis 2008 hat gezeigt, dass die GrundsÃ¤tze der NÃ–T unverÃ¤ndert ihre GÃ¼ltigkeit haben. Das wesentlich gÃ¼nstigere Systemverhalten zeigt jedoch deutlich, dass sich die Kenntnisse in Planung und AusfÃ¼hrung stark weiterentwickelt haben. Der grÃ¶ÃŸte Unterschied zeigt sich aber bei der ErhÃ¶hung der ProduktivitÃ¤t und wird durch den Vergleich der Produktionsmittel offenkundig.
