摘要
This paper presents an elastoplastic model for unsaturated rocks and concrete. The formulation is based on the poroplastic theory of porous media. The effect of water saturation on plastic deformation is described through a generalised effective stress. Plastic shrinkage and swelling due to suction change are taken into account. All model's parameters can be determined from specific laboratory tests. Comparisons between numerical simulations and experimental data are provided for a claystone. (C) 2002 Elsevier Science Ltd.
