Design -- Installations in tunnels -- Investigation and description of the ground -- Heading -- Support -- Grouting and freezing -- The New Austrian Tunnelling Method -- Management of groundwater -- Application of compressed air -- Subaqueous tunnels -- Shafts -- Safety during construction -- Tunnelling Mechanics -- Behaviour of soil and rock -- Stress and deformation fields around a deep circular tunnel -- Supporting action of anchors/bolts -- Some approximate solutions for shallow tunnels -- Stability of the excavation face -- Earthquake effects on tunnels -- Settlement of the surface -- Stability problems in tunnelling -- Monitoring -- Numerical analysis of tunnels. The book covers not only practical aspects but also the underlying theoretical approaches. It also covers the fundamentals of rock mechanics. It addresses not only students but also professionals who are interested to understand the underlying principles and methods and - possibly - to further develop them. Emphasis is given to the mechanical approach rather than to hardly tractable empirical statements. The text is concise and comprises a large list of citations. Publications of the English and German speaking scientific communities have been taken into account.
