Liquefaction-induced slope instability represents a critical hazard in geotechnical engineering, particularly under seismic loading conditions. This paper investigates the numerical simulation of a water-saturated, liquefiable sandy slope subjected to dynamic base excitation, based on centrifuge test data. Advanced constitutive models are applied to reproduce the coupled hydro-mechanical response, including pore pressure build-up, stiffness degradation, and large deformations. The simulations are evaluated against experimental observations, highlighting the capabilities and limitations of current modelling approaches in capturing liquefaction triggering and slope failure. The results contribute to an improved understanding and prediction of liquefaction-induced instabilities in slopes.
