VULNERABILITY OF TRAFFIC EMBANKMENTS TO LIQUEFACTION-INDUCED DEFORMATIONS

Oblak Aleš; Logar Janko; Kuder Sebastjan; Viana da Fonseca Antonio

Liquefaction-induced deformations on traffic embankments were studied using software package FLAC in combination with advanced material model PM4Sand in order to simulate the liquefaction phenomenon. A parametric study was carried out, where the geometry of the embankment and soil profile was varied. In addition, numerical analyses were performed for two sets of material properties of the liquefiable sandy layer – medium dense and loose state. On the basis of numerical results, fragility curves were derived in terms of crest settlement as damage state parameter and Arias intensity or peak ground acceleration as intensity measure.
