Popis:	The model of a saturated porous medium with a brittle deformable skeleton is formulated in an isothermal approximation. The general form of governing equations is found, which is necessary and sufficient to fulfill the principles of objectivity and thermodynamic consistency. It is shown that the kinetics of developing the ensemble of microcracks, determined by the derivative of the elastic potential of the skeleton with respect to the fracture parameter, results in a nonnegative dissipation of the scattered destruction with any type of loading. For small deviations from the initial state, a new elastic potential is proposed which has made it possible to describe the main irregularities of the behavior of the medium in question. The solution of the problem about the consolidation of a saturated porous half-space with a brittle skeleton under a normal load has been constructed.
