Hardrock Tunnel Boring Machines

This book covers the fundamentals of tunneling machine technology: drilling, tunneling, waste removal and securing. It treats methods of rock classification for the machinery concerned as well as legal issues, using numerous example projects to reflect the state of technology, as well as problematic cases and solutions. The work is structured such that readers are led from the basics via the main functional elements of tunneling machinery to the different types of machine, together with their areas of application and equipment. The result is an overview of current developments. Close cooperation among the authors involved has created a book of equal interest to experienced tunnelers and newcomers.

Dieser Band behandelt die Grundlagen der Tunnelbautechnologie: Bohrung, Tunnelvortrieb, Abtransport und Entsorgung des Abraums sowie Sicherungsmaßnahmen. Methoden zur Klassifikation von Gesteinen und technische Einzelheiten der Maschinen werden ebenso diskutiert wie juristische Aspekte. Zahlreiche Beispiele reflektieren den modernen Stand der Technik, illustrieren Anwendungen und veranschaulichen Problemfälle. Das erfahrene, erfolgreiche Autorenteam wendet sich gleichermaßen an erfahrene Tunnelbauer und interessierte Neueinsteiger.
