The Proceedings of EUROCK 2010 is a collection of 6 keynotes and 193 technical papers accepted by the symposium. As an annual European regional event of the International Society for Rock Mechanics (ISRM), EUROCK has been a major exchange and discussion platform for the international rock mechanics community. Rock mechanics in Europe has been undergoing some major transformation during the last two decades. The reduction of mining activities in Europe affects heavily on rock mechanics teaching and research at universities and institutes. At the same time, new merging activities, notably, underground infrastructure construction, geothermal energy development, radioactive waste and CO2 repository, and natural hazard management, are creating new opportunities of research and engineering. Rock mechanics today is closely associated with, and indeed part of, construction, energy, and environmental engineering. The scheme of EUROCK 2010 is chosen to be “Rock Mechanics in Civil and Environmental Engineering”, to reflect the belief of the symposium organiser on the future of rock mechanics. This is responded positively and overwhelmingly. The symposium received altogether over 340 abstracts, of which 193 papers are finally published in this proceedings volume. The papers in the proceedings are organised in 5 parts: keynote papers, fundamental rock mechanics, tunnels and underground structures, rock slopes and landslides, resources and environment. Each part is further divided to include papers of closely related topics.
