20.500.12556/DKUM-70682 Development and analysis of 3D geological/geomechanical models for pumped hydroelectric power plant Kozjak Razvoj in analiza 3D geološko/geomehanskih modelov za črpalno elektrarno Kozjak In order to specify the geological and geotechnical conditions for the construction of the Kozjak pumpedstorage hydroelectric power plant (HPP), the site area has undergone considerable geological, geophysical and geomechanical investigations. Due to the complexity of the geotechnical constructions and the size of the investigated site a novel approach was proposed, where the results of the investigation were used to develop 3D geological/ geomechanical models. The models were created with the integration of all the available results and data into typical geomechanical units that were subsequently given spatial dimensions. Through an analysis of the models the relationships between the different units were better understood and the critical areas were quickly identified and verified. In this paper the models for the accumulation reservoir and the engine room are presented. The overview of the executed investigations and the results are given together with a discussion on the scope and the number of executed investigations from the standpoint of the 3D geological/geomechanical model’s creation. Za določitev geoloških in geotehničnih pogojev gradnje črpalne elektrarne ČHE Kozjak smo izvedli obsežne geološke, geofizikalne in geotehnične preiskave. Rezultati preiskav so bili uporabljeni za razvoj in izdelavo 3D geološko/geomehanskih modelov. Modeli so bili izdelani z združitvijo vseh razpoložljivih podatkov v značilne geomehanske enote, ki so bile v naslednjem koraku postavljene v prostor skupaj s predvideno geotehnično konstrukcijo. Tak pristop je bil izbran zaradi kompleksnosti geotehničnih objektov in velikosti preiskovanega območja. S pomočjo prostorske analize je mogoče lažje razumeti odnose med posameznimi enotami in elementi, ter hitro ugotoviti najbolj kritična območja s stališča geotehnične konstrukcije in jih tudi stabilnostno preveriti. V članku sta prikazana modela za akumulacijski bazen in strojnico. Predstavljen je tudi pregled opravljenih preiskav skupaj z rezultati, ter razpravo o obsegu in vrsti preiskav z vidika izdelave 3D geološko/geomehanskih modelov. geological investigations geomechanical investigations 3D geological-geomechanical models HPP Kozjak geološke preiskave geomehanske preiskave 3D geološko-geomehanski modeli ČHE Kozjak true false true Angleški jezik Slovenski jezik Fakulteta za gradbeništvo, prometno inženirstvo in arhitekturo Univerze v Mariboru Znanstveno delo 2018-06-06 09:43:56 2018-06-06 09:45:09 2022-08-01 19:40:37 2019-07-11 18:16:03 2009 0 0 str. 20-33 št. 1 Letn. 6 2009 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1854-0171 550.8 215987712 1365987 1854-0171 URN:SI:UM:DK:QRTELX5Z Acta_geotechnica_Slovenica_2009_Development_and_analysis_of_3D_geological_geomechanical_models.pdf Acta_geotechnica_Slovenica_2009_Development_and_analysis_of_3D_geological_geomechanical_models.pdf 1 2AD81789FD6AD5453F2D28B0B7D39AE9 c16f3282fa786ea65e56c128404a19aa691820a3e5dcfc9d75dd4f0b4673d845 009e4295-7c10-11eb-bb7a-00155d0001ca 20.500.12556/dkum/1826afdd-8df0-4b6d-b089-a6c44e33f8d2 https://dk.um.si/Dokument.php?lang=slv&id=125315 http://fgserver3.fg.um.si/journal-ags/2009-1/article-2.asp 1 https://dk.um.si/Dokument.php?lang=slv&id=125314 Fakulteta za gradbeništvo, prometno inženirstvo in arhitekturo Acta geotechnica Slovenica 0 0 0
