Tunnelling technology in Norway, with particular emphasis on deep subsea tunnels

Bjørn Nilsen, Professor of Geological Engineering at the Norwegian University of Science and Technology (NTNU) and Henki Ødegaard, Ph.D. candidate at the Norwegian University of Science and Technology (NTNU).

Tunneling activity in Norway has remained at a high level for a long period, with an average of about 5 mill. M3 excavated annually. The activity of a wide range of different projects will be discussed.

Tunnels under sea represents a challenge due to the difficult ground conditions encountered. More than 50 such tunnels in Norway are for road purposes. Characteristics of subsea tunnels will be discussed. A case history of remedial measures required after instability/cave-in 250 m below the ocean, and aspects of a 27 km, twin- tube tunnel project at a depth of more than 350 m will be presented.

A description of HydroCE, will be given. Hydropower tunnelling is very important for the development of Norwegian tunnelling technology, and there is an increased interest in hydropower development. Flexible operation and balancing power are a focus that cause increased demand for R&D.
