20.500.12556/DKUM-70857 Evaluation of the plastic critical depth in seismic active lateral earth pressure problems using the stress-characteristics method Vrednotenje plastične kritične globine za probleme seizmičnih aktivnih bočnih zemeljskih pritiskov z metodo napetostnih karakteristik The plastic critical depth or the conventional tension crack depth has a considerable effect on the active lateral earth pressure in cohesive soils. In this paper the depth for c-ϕ soils has been evaluated in the seismic case using the stress-characteristics or slip-line method. The plastic critical depth was calculated on the basis of the theory of the stress-characteristics method and by considering the horizontal and vertical pseudo-static earthquake coefficients. The proposed solution considers the line of discontinuity in the stress-characteristics network. The earth slope, wall slope, cohesion and friction angle of the soil and the adhesion and the friction angle of the soil-wall interface were considered in the analysis as well. The results show that the plastic critical depths of this study are smaller than those of the other methods and are closer to the modified Mononobe-Okabe method. The effects of the wall and the backfill geometry, the mechanical properties of the soil and the pseudo-static coefficients were studied. Plastična kritična globina ali običajno imenovana globina natezne razpoke ima precejšen vpliv na aktivne bočne zemeljske pritiske v koherentnih tleh. V prispevku je globina za c-ϕ zemljino določena za primer potresa z uporabo napetostnih karakteristik ali metodo porušnic. Plastična kritična globina je bila izračunana na podlagi teorije metode napetostnih-karakteristik in ob upoštevanju horizontalnih in vertikalnih psevdo-statičnih potresnih koeficientov. Predlagana rešitev obravnava črto diskontinuitete v mreži napetostnih karakteristik. V analizi so bili prav tako upoštevani naklon zaledja in zidu, kohezija in notranji kot trenja ter tudi adhezija in kot trenja na površini med zemljino in zidom. Rezultati kažejo, da so plastične kritične globine te študije manjše od drugih metod in so bližje modificirani metodi Mononobe-Okabe. plastic critical depth stress characteristics active lateral earth pressure seismic morska erozija stabilnost klifov SfM fotogrametrija otok Krk Jadransko morje true false true Angleški jezik Slovenski jezik Fakulteta za gradbeništvo, prometno inženirstvo in arhitekturo Univerze v Mariboru Znanstveno delo 2018-06-15 14:32:41 2018-06-15 14:33:35 2023-07-31 09:14:14 2019-07-11 18:22:11 2016 0 0 str. 17-25 št. 1 Letn. 13 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1854-0171 624.13 215987712 302729472 1854-0171 URN:SI:UM:DK:GWAHP3YZ Acta_Geotechnica_Slovenica_2016_Keshavarz_Evaluation_of_the_plastic_critical_depth_in_seismic_active_lateral_earth_pressure_problems_usi.pdf Acta_Geotechnica_Slovenica_2016_Keshavarz_Evaluation_of_the_plastic_critical_depth_in_seismic_active_lateral_earth_pressure_problems_usi.pdf 1 C20E7075AECCD6F34616CBE0C14B2DB3 e9f2c43d833f3d68ac1b8f9beaf01a4b1816bba34163d786616ecb5d9d2cd26f 0abcea71-7c10-11eb-bb7a-00155d0001ca 20.500.12556/dkum/7e85af55-a675-4e8b-903f-575b2d864a29 https://dk.um.si/Dokument.php?lang=slv&id=125764 http://fgserver3.fg.um.si/journal-ags/2016-1/article-2.asp 1 https://dk.um.si/Dokument.php?lang=slv&id=125763 Fakulteta za gradbeništvo, prometno inženirstvo in arhitekturo Acta geotechnica Slovenica 0 0 0
