In earthquake engineering practice, the site effect simulation is evaluated based on the geometry and stratigraphy of the site, the characterization of the soil properties and the ground motions records. Usually, to identify the soil characterization, laboratory or in-situ tests take place (i.e. triaxial tests, direct shear tests, CPT or SPT …). In order to simulate these tests and in case of absence of experimental tools, numerical models can represent the response of the soil. Liquefaction, till our days, is considered as one of the most complex behaviors that happen to the soil due to sudden and severe shakings. The aim of this paper is to conduct "virtual" laboratory tests on soil samples extracted from the foundation of an embankment. They serve to a better representation of the realistic case of the soil taking into account complex input data and to a comparison with the laboratory tests for the purpose of understanding the global soil response. The numerical model used is an elasto-plastic multi-mechanism model to represent the soil behavior.
