. Prof. Konietz§ is one of the pioneers in using particle-based approaches to solverock-mechanical problems. Firstpublication goes backto 1996 togetherwith Peter

Cundall and David Potyondy (Cnntlail, P.: Konietzki,, l{.: PotlLrncly" D., { I996); PF{' - t:in

uçu*.q í4,-arkre ug /tn" ruru*t'ist:lte tr,lutÍdlir:rwnguru. Dautechnik. ?3/8: 4q2-5t)0). Over the past

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

r Research in deep geothermal energy: within several big research projects, Prof.Konietz§ is involved in the development of new approaches to create highlyeffective underground heat exchangers with reduced induced seismicity based onnewly developed numerical simulation approaches, lab tests and fieldobservations/measurements. He explained, how multi-fracture system should be

designed (e.g. Z*eb, {1.. Konistzky, H. {20 l5\'. ,\inruluÍing tha h3uh'uulit: sti,muíution r$'nulti1tle

7{t: 2h4-272) and has developed procedures to predict vibration velocities due toinduced seismicity.

. Development of a geogrid-modelling approach based on particle-based clumptechnology to consider rock-ballast-geogrid interlocking. Teaching of thismodelling approach by Prof. Konietz§ at Nottingham University (GB) andUniversity of Illinois (USA) was the basis for dozens of international publicationsabout this topic by researchers worldwide. Through this procedure, first time, theinterlocking mechanisms were detected in a quantitative manner (c.g. Konietzky" i t.;

sttrlit' ttrtd t,t;rlit: htutling. hlumerical Modeling in Miçtçmechaniçs via Partiçle Methficls"

Ilalkenra. pp. l- l I ). Now, this procedure is widely used for dimensioning and productdevelopment.

Development, construction and use of a worldwide unique dynamic hydro-mechanical coupled big shear box device called GS-1000 (e.g. Konietzky, H.;

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

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.
