"Eurocode 7: genesis, development and implications for rock engineering"
During the course of the past decade a somewhat revolutionary approach to geotechnical engineering design has appeared, in the form of the design code EN-1997 Geotechnical Design, popularly known as Eurocode 7, or EC7. This article reviews the development of EC7 and the basis of the design philosophy it embraces, namely Limit State Design (LSD), before going on to show how LSD is currently implemented within EC7. Following this, the key issues of applying LSD to rock engineering design are explored, before closing with a review of how the forthcoming revision of EC7 – planned for 2020 – will display improved applicability to rock engineering design. Throughout these Sections, areas where customary rock engineering design practice will need to evolve in order to be compliant with the principles of LSD are highlighted.
John Harrison's research and professional interests lie principally in the field of rock engineering design techniques. For the past decade he has been actively working on the development of limit state design principles for engineering in fractured rock masses. As part of this he currently chairs a specialist pan-European rock mechanics and rock engineering expert group working under the auspices of CEN to revise Eurocode 7. In addition, he chairs the ISRM Commission on the Evolution of Eurocode 7. He currently holds the W.M. Keck Chair of Engineering Rock Mechanics at the University of Toronto, Canada, which position he has held since 2010.
