Abstract
The authors construct a continuum approximation for the model of a medium with internal structure and internal self-balancing stresses. The presupposition of diffeomorphism, i.e. existence of partial space derivatives of displacements is largely slackened. The information brought to the closed model of a geomedium by this presupposition is comparable with the information brought by the constitutive equations. The new model includes the local bends of grains of the skeleton, plasticity and the elastic strains of the binding medium in the pore space. The model is of a gradient type.
