The paper deals with the seismic stability assessment of an existing zoned earth dam using a fully-coupled effective stress non-linear approach implemented in a finite element (FE) code. The mechanical behaviour of soils forming both the core and shells is described through advanced elasto-plastic constitutive models, calibrated on experimental results relative to the embankment materials. As the initial stress state and model internal variables play a crucial role on the results of the dynamic simulations, appropriate FE static analyses of the dam are performed prior to the application of the seismic motion at the bedrock. Finally, the stability of the dam during and after two different earthquakes is evaluated.
