20.500.12556/DKUM-70876 A comparison of linear and nonlinear seismic tunnel-ground interaction analyses Primerjava linearne in nelinearne seizmične interakcijske analize predor-tla In order to study the effects of a seismically induced tunnel–ground interaction, two-dimensional numerical analyses are performed using the sofware ANSYS. The study employs a coupled beam–spring model subjected to earthquake loading that is simulated under pure shear conditions and determined by a free-field ground-response analysis using the code EERA. The properties of the soil material are considered as both linear and nonlinear. The results obtained by linear dynamic analyses are compared with state-of-practice analytical elastic solutions. A comparison of the results of both linear and nonlinear analyses is also performed, and significant differences, as well as important factors influencing the tunnel–ground interaction for both cases, are evaluated. Članek preučuje potresne učinke na interakcijo predor-tla. Za to so bile izvedene dvodimenzionalne numerične analize s pomočjo programa ANSYS. V študiji je uporabljen potresno obremenjen združeni model nosilec-vzmet, ki je simuliran pod čistimi strižnimi pogoji in določen z analizo odziva tal s prostim poljem z uporabo programske kode EERA. Lastnosti materiala tal so obravnavane tako linearno kot nelinearno. Rezultati, dobljeni z linearnimi dinamičnimi analizami so primerjani z v praksi znanimi analitičnimi elastičnimi rešitvami. Primerjani so tudi rezultati linearnih in nelinearnih analiz, za oba primera so ovrednotene pomembne razlike ter pomembni dejavniki, ki vplivajo na interakcijo predor-tla. circular tunnel linear/nonlinear soil behaviour beam–spring model plane-strain conditions simplified dynamic FE analysis soil–structure interaction predor okroglega prereza linearno / nelinearno obnašanje tal model nosilec-vzmet ravninsko-deformacijski pogoji poenostavljena dinamična analiza s končnimi elementi interakcija tla-konstrukcija true false true Angleški jezik Slovenski jezik Fakulteta za gradbeništvo, prometno inženirstvo in arhitekturo Univerze v Mariboru Znanstveno delo 2018-06-18 08:53:10 2018-06-18 08:54:25 2023-07-31 09:23:54 2019-07-11 18:22:49 2016 0 0 str. 27-42 št. 2 Letn. 13 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1854-0171 215987712 302919424 1854-0171 URN:SI:UM:DK:QQ8WHA7Z Acta_geotechnica_Slovenica_2016_Zlatanovic_et_al._A_comparison_of_linear_and_nonlinear_seismic_tunnel–ground_interaction_analyses.pdf Acta_geotechnica_Slovenica_2016_Zlatanovic_et_al._A_comparison_of_linear_and_nonlinear_seismic_tunnel–ground_interaction_analyses.pdf 1 60FF450D7BC02071CAFF73CD3C99F48B 1aacf66693bc3301c3ddb1bff828a1444ccbd3b2cd01520b6bd63d7f7c6c9e81 0bcc6a85-7c10-11eb-bb7a-00155d0001ca 20.500.12556/dkum/4a859c84-a695-4497-98f2-4ea813dc08af https://dk.um.si/Dokument.php?lang=slv&id=125821 http://fgserver3.fg.um.si/journal-ags/2016-2/article-3.asp 1 https://dk.um.si/Dokument.php?lang=slv&id=125820 Fakulteta za gradbeništvo, prometno inženirstvo in arhitekturo Acta geotechnica Slovenica 0 0 0
