Abstract
Nonuniformity of a medium shows itself in many characteristics, including Young modulus, Poisson ratio, shear modulus, as well as limit elasticity and limit plasticity. The article shows that introduction of the nonuniformity of properties allows studying hierarchical block structure of a medium in different geomechanical problems and estimating effect of the blocky structure on the stress state of rock mass.
