Author Information

Nick Barton began his employment at the Norwegian Geotechnical Institute (NGI). He was a Division Director for 5 years and a Technical Advisor for 10 years in the Dam, Rock Tunnel, Avalanche and Reservoir Divisions. From 1980 to 1984, he worked in the Geomechanics Division of Terra Tek in Salt Lake City, USA. He has taught at the University of Sao Paulo since 1997 and since 2001 has had his own international consultancy, based in Oslo and Sao Paulo. Nick Barton developed the widely used Q-system for classifying rock masses and for selecting rock tunnel and cavern support in 1974, and was co-developer of the Barton-Bandis constitutive laws for rock joint computer modelling in 1982.
