20.500.12556/DKUM-70779 Numerical modeling of floating prefabricated vertical drains in layered soil Numerično modeliranje plavajočih montažnih navpičnih drenaž v večplastni zemljini This paper presents a comparison of field measurements and a numerical model of settlements based on the construction of an embankment on soft soil for the Cirebon Power Plant Project in Indonesia, where prefabricated vertical drains (PVDs) were installed. In the numerical model, floating PVDs in two soil layers for two- and one-way drainage conditions are examined in order to determine the optimum penetration depth. In this study, good agreement between the field measurements of the settlements and the numerical prediction could be achieved. An interesting result of this study is that the differences in the stiffness and/or the permeability in the unimproved area below the PVD tip have a significant influence on the optimum penetration depth (L/H) in the two-soil-layer condition. The numerical study showed that it is possible to use floating PVDs in single drainage conditions if the second layer is stiffer and/or more permeable than the first layer. Članek prikazuje primerjavo terenskih meritev in numerični model posedanja nasipov na mehkih tleh v okviru indonezijskega projekta Cirebon Power Plant, kjer so bile nameščene montažne vertikalne drenaže (MVD). Za določitev optimalne globine namestitve drenaž so bile z numeričnim modelom preučene plavajoče MVD v dvoslojnih tleh pri pogojih dreniranja v eni in obeh plasteh. Študija je pokazala dobro ujemanje terenskih meritev posedanja z numeričnimi napovedmi. Zanimiv rezultat študije je, da razlike v togosti in/ali prepustnosti neizboljšane zemljine pod konico MVD pomembno vplivajo na optimalno penetracijsko globino (L/H) v dvoslojnih tleh. Numerična študija je pokazala, da se lahko plavajoče MVD uporabijo za enojno drenažo, če je druga plast bolj toga in/ali bolj prepustna kot prva plast. two soil layers floating prefabricated vertical drain double and single drainage numerical model soft clay consolidation geofizika geotehnika nasipi posedanje drenaža glina numerični modeli meritve Indonezija dvoslojna tla plavajoče montažne vertikalne drenaže dvojna in enojna drenaža mehka glina konsolidacija true false true Angleški jezik Slovenski jezik Fakulteta za gradbeništvo, prometno inženirstvo in arhitekturo Univerze v Mariboru Znanstveno delo 2018-06-13 11:55:29 2018-06-13 11:57:30 2022-08-01 19:48:47 2019-07-11 18:19:36 2012 0 0 str. 25-35 št. 2 Letn. 9 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1854-0171 550.3:624.136.2 215987712 270604544 1854-0171 URN:SI:UM:DK:NSRFZMCV Acta_geotechnica_Slovenica_2012_Ikhya,_Schweiger_Numerical_modeling_of_floating_prefabricated_vertical_drains_in_layered_soil.pdf Acta_geotechnica_Slovenica_2012_Ikhya,_Schweiger_Numerical_modeling_of_floating_prefabricated_vertical_drains_in_layered_soil.pdf 1 E42A11470C01183FA09499FA19B28BD8 9b756c22ce64c023ffc893badc207bd1044122b64e6108489d16fe85eca820ec 0671728f-7c10-11eb-bb7a-00155d0001ca 20.500.12556/dkum/debdada2-5b19-4778-8f15-49091a41833c https://dk.um.si/Dokument.php?lang=slv&id=125589 http://fgserver3.fg.um.si/journal-ags/2012-2/article-3.asp 1 https://dk.um.si/Dokument.php?lang=slv&id=125590 Fakulteta za gradbeništvo, prometno inženirstvo in arhitekturo Acta geotechnica Slovenica 0 0 0
