Title:	Development trends in mechanised tunnelling / Entwicklungstendenzen im maschinellen Tunnelbau
Abstract:	This article reports on the development of tunnel boring machines (TBMs) in the past decades and the current state of the art. The development is presented with a look back and a look forward into the near future. Starting with the questions on the development of diameter and operating pressure of closed tunnelling machines, the perspective is expanded to general developments and current trends in machine technology for soft ground and hard rock. Finally, the possibilities and potentials arising from environmental requirements, further increases in performance and digitalization in mechanized tunnelling are shown. Der Beitrag berichtet über die Entwicklung von Tunnelvortriebsmaschinen (TVM) in den vergangenen Jahrzehnten und zeigt den aktuell erreichten Stand auf. Dabei wird die Entwicklung jeweils mit einem Blick zurück und einem Ausblick in die nähere Zukunft dargestellt. Beginnend mit den Fragestellungen zur Durchmesser- und Betriebsdruckentwicklung geschlossener Vortriebsmaschinen wird der Blickwinkel auf allgemeine Entwicklungen und aktuelle Tendenzen der Maschinentechnik für Locker- und Hartgestein erweitert. Abschließend werden die Möglichkeiten und Potenziale aufgezeigt, die Umweltanforderungen, weitere Leistungssteigerungen und Digitalisierung im maschinellen Tunnelbau bieten.
