“…Many types of river dikes and embankments have been analyzed through the strain space multiple shear mechanism model and mostly successful in reproducing the varying degree of crest settlements depending on the geotechnical condition of foundation (Ozutsumi et al, 2002;Tobita et al, 2006a). However, recent experience in analysis of one particular type of river dike, the dike No.1 of the Shiribeshi-Toshibeshi river, Hokkaido, Fig.…”

“…Greater discrepancies may therefore exist amongst LEP predictions in the assessment of silty sands and sandy silts, relative to evaluations of clean sands. Lastly, field, laboratory, and numerical analyses have suggested that high fines-content soils in the capping or interbedded non-liquefiable strata may inhibit surficial liquefaction manifestations [45,4,39]. Thus, inherent limitations in the LPI framework to account for such effects may lead to erroneous hazard assessments even if the selected LEP is wholly competent.…”

“…As in the case of the soil column, parametric studies are conducted in order to explore the influence of the characteristics of the input motion, soil permeability and the thickness of the liquefiable layer on the failure mechanism. In fact, in the past several studies have been proven the crtical role of the influence of foundation soil type and earthquake characteristics [20,1,13,15].…”

Abstract. Soil structures such as river dikes, highway embankments, and earth dams have been frequently damaged during past major earthquakes. In most cases, large deformations occurred due to liquefaction of the supporting loose cohesionless foundation soil, resulting in cracks, settlement, lateral spreading, and slumping. Some researchers showed that river levees resting on non-liquefiable foundation soil have been damaged. In this regard, the base of such levees subsided in a bowl shape due to foundation consolidation that was shown to have the principal contribution to liquefaction as an underlying mechanism. This paper aims at describing the global dynamic response of a thin Loose Sand layer located buried in deep (10m) stratum of Clay (less permeable), situated at the foundation of a levee, due to liquefaction phenomenon. This study purpose is to reproduce such behavior by applying numerical simulations, adopting the open-source computational platform OpenSees. In particular, this study considers a 2D soil model of a levee subjected to earthquakes in order to investigate the failure of embankments induced by non-liquefiable soil foundation with a thin sand layer with partially drained condition. A parametric analysis using ground motions at multiple levels of intensity was performed to highlight the influence of parameters such as, the thickness of saturated zone, the permeability ratio between saturated zone and non-liquefiable soil (i.e. drain condition) on the obtained crest settlement and on the induced damage level of the embankment.
