Title:	Ground reaction and lining curves / Gebirgs- und Ausbaukennlinien
Abstract:	Ground reaction curves characterise the behaviour of the ground while excavating and supporting the cavity and provide a better understanding of the resulting interactions of ground pressure, lining loading and deformation. By including the element of time, the picture can be extended to a diagram, which can be used to display or understand certain situations better. A few practical examples should help to understand the reasons for failure or the failure mechanism. Gebirgskennlinien charakterisieren das Verhalten des Gebirges beim Öffnen und bei der Sicherung des Hohlraums und ermöglichen einen besseren Einblick in die daraus resultierenden Zusammenhänge von Gebirgsdruck, Ausbaubelastung und Verformung. Durch Einbeziehung der Zeitkomponente wird das Bild zu einem Diagramm erweitert, wodurch bestimmte Situationen besser dargestellt bzw. nachvollzogen werden können. Einige Beispiele aus der Praxis sollen dazu beitragen, die Gründe des Versagens bzw. den Versagensmechanismus zu verstehen.
