years his research topics covered rock- and soil-mechanical problems like fractureand damage evolution, mass movements, hydro-mechanical coupled simulations orhydrofrac propagation simulation.

Development, construction and use of a worldwide unique dynamic hydro-mechanical coupled big shear box device called GS-1000 (e.g. Konietzky, H.;
Rock Meçhanír:s Rock Engineering, 4513: 427 -432).
lntegrated approach of stress field modelling and stress measurements: Prof.Konietzky has consequently combined hydrofrac stress measurements and
numerical stress field modelling to obtain reliable stress field information, startingalready in 1991. Through several exceptional field studies he documented the
complexity of in-situ stress fields in rockmasses (e.g. Konietzky, I{.; te Karnp, 1..;

Rumrnel, F., OrÍbrcl & IIIH Publishing. pp. 55-80).
. Numerical simulations for Opalinus Clay as host rock for radioactive wasterepositories: Since already 1992 Prof. Konietzky is involved in research aboutgeomechanical aspects in using Opalinus Clay as host rock for radioactive wastestorage. His work, mainly done for NAGRA, EU and France covered severaltopics, like constitutive modelling development, data compilation, stress fieldmodelling, HTM-coupled behavior, backfilling and research projects in Mt. Terriand Bure-Site (e.g. Bock, H.l Bliinrling, P.; Konietzky. H.. (2006): Studl; o-/' rhe
Proc. European Commission Cluster Conference on lmpact of llDZ on the perÍi:rmance ofraclicractive *,aste seological repositories. pp.237-241). Basic geomechanical concepts,especially in Súitzerland, are still based to a considerable amount on hiscontributions. He,is still working as senior consultant/expert for NAGRA.

Prof. Konietzky is supervisor of PhD students and Post-Doc students from Germany, Austria, Australia,Spain, China, Vietnam, Pakistan, India, Egypt and Nepal (13 already successfully finished, several ofthem awarded). He has given invited lectures and training seminars at several universities and research
centers in Germany, Belgium, France, Austria, China, India and Vietnam. He was keynote speaker athigh-level intemational conferences and is the editor of 2 books and the author of more than 100
international publications. Hp worked as Guest Professor at Tongji University, Shanghai, University ofGeosciences, Beijing and Henan Polytechnic University, Jiaozuo. He is working as reviewer and adviserfor several institutions, for instance for Mining Authorities and Radioactive Waste Organizations inEurope. He is scientific boarâ member of TAML and JRMGE, was core member of FIGES (Federationof Int. Geoengineering Societies) frop 2008-2012 and is member of EGEP (European Geogrid ExpertPanel) since 2007. He is supervisor of three post-doc students, awarded with the Humboldt-Fellowship.Prof. Konietzky is involved in several big research projects §ational, EU, 111-Projects in China etc.).
