Paper Abstract

Stress-strain plane state of granular-elastic layered media is under investigation. Several horizontal granular layers are laying on an elastic one, which is weakened by a round hole. The attention is paid to evaluating the upper surface displacements. The Kandaurov's model of stresses in granular medium is used. The displacements of grains are described by the generalized Litwiniszyn-Muller's model. Authors have introduced the stresses into the stochastic equations for the trajectories of grains. General problem is reduced to three sequentially solved ones: (1) evaluating stresses in the granular layers; (2) solving stress-strain problem for the elastic layer; (3) calculating the displacements in granular layers.
