This work focuses on the behaviour of porous triphasic media, particularly on unsaturated soils subjected to hydromechanical loading. A coupled elastoplastic constitutive model has been developed. This original model is formulated according to the following principles: (1) a constitutive law describing the behaviour of different phases (solid skeleton, liquid and gas). (2) coupling relationships between each phase. For the behaviour of the solid skeleton, a non associated elastoplastic constitutive law is adopted, with two loading surfaces: shear surface and compression cap surface. The hydric part is discribed using a formulation which allows to take into account the hysteresis effect. This model has been extended using a hydromechanical c...
