20.500.12556/RUL-124817 Fragility assessment of traffic embankments exposed to earthquake-induced liquefaction In this study, a vulnerability analysis of road and railway embankments to earthquake-induced liquefaction deformations was carried out. The result of the vulnerability analysis was a set of fragility curves that were obtained for several embankment and soil-profile geometries, as well as for the material properties of the liquefiable layer. The fragility curves were based on the numerical calculations obtained from FLAC 2D software in conjunction with the PM4Sand material model used for simulating the behavior of liquefaction-susceptible soils during dynamic shaking. The fragility analysis was performed using an incremental dynamic analysis approach considering a set of 30 ground motions and at least eight intensity levels. Permanent vertical displacement of the middle top point of the embankment was selected as the damage parameter, while the intensity measure was expressed in terms of peak ground acceleration at bedrock. Fragility curves were derived for three damage states, including minor, moderate and extensive damage, based on threshold values proposed in the literature. The influence of a single model variable was examined through comparison of the fragility curves. civil engineering soil liquefaction fragility curve traffic embankment FLAC PM4Sand gradbeništvo likvifakcija tal krivulja ranljivosti nasipi prometnic FLAC PM4Sand true false true Angleški jezik Slovenski jezik Članek v reviji 2021-02-19 16:50:04 2021-02-19 16:50:09 2022-09-04 04:01:38 0000-00-00 00:00:00 2020 0 0 19 str. iss. 19, art. 6832 Vol. 10 2020 0000-00-00 Zaloznikova Objavljeno apc 0000-00-00 0000-00-00 0000-00-00 624 2076-3417 10.3390/app10196832 30533379 RAZ_Oblak_Ales_2020.pdf RAZ_Oblak_Ales_2020.pdf 1 4035EC247AA6416E5B367A9F167E5005 b5e0dba2ea340c2e316faf5cc540730d399cff2962046d296f16ea386aa1353f 132c6b28-7aaa-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=153151 https://www.mdpi.com/2076-3417/10/19/6832 0 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=140435 Fakulteta za gradbeništvo in geodezijo 0 0 0
