• This paper describes an elastoplastic model for rockfills and simulations of laboratory test by using the model. Rockfills express remarkable shear strength reductions and compressive deformations due to saturation. The authors have already developed elastoplastic models to represent the mechanical properties of unsaturated soils. Two suction effects were taken into account in the models. However for rockfills, one suction effect: an increase in suction enhances yield stresses and affects resistance to plastic deformations, remarkably appears. The effect may be evaluated by formulating state surfaces. In this paper, a model proposed by authors is modified for rockfills. To verify the elastoplastic model for rockfills, simulations of oedometer and triaxial compression tests were carried out. The simulation results could well express the volume change and shear behavior of the rockfill, especially the influence of water contents.
