Title:	Requirements for the observational approach in deep tunnelling - Anforderungen an die Beobachtungsmethode bei tiefliegenden Tunneln
Abstract:	The author shortly reviews the requirements of the Eurocode 7 regarding the Observational Method for use during tunnel construction. The particularities and problems of applying the Observational Method at deep tunnels are listed. A recommendation is given to improve the situation and to bring the approaches used in normal ground engineering problems and deep tunnels closer together. Zunächst werden die Anforderungen des Eurocodes 7 hinsichtlich der Anwendung der Beobachtungsmethode im Tunnelbau kurzbetrachtet. Anschließend werden die Besonderheiten und Probleme bei deren Anwendung bei tiefliegenden Tunneln analysiert. Dabei zeigen sich wesentliche Unterschiede zu anderen bodenmechanischen Anwendungen. Schließlich werden Empfehlungen gegeben, wie die Anwendung der Beobachtungsmethode verbessert und die Vorgangsweisen vereinheitlicht werden können.
