Tunnelling and ground conditions

The planning, design, construction and cost of tunnels depend, to a large extent, on the ground conditions likely to be encountered. As ground conditions can be both numerous and varied, research and innovative methods of construction are all focused on the need to conquer both the expected and unexpected difficulties likely to be encountered which will always remain a tunneller's challenge. This text contains 89 papers by experts in the design and construction of tunnels and other underground structures, which provide information on various aspects of tunnelling in different ground conditions. The papers emcompass many aspects of tunnelling including recent case histories of major projects, tunnelling through water-bearing deposits, underground projects of rock formations, recent research and development of underground space, numerical and experimental modelling of tunnels, repair of tunnels, management of underground projects and other general tunnelling topics.
