| The steady vibrations of a rigid block based on the porous liquid-saturated base with viscoelastic solid skeleton are investigated. Block is subjected by the horizontal force or the torque. The equations of two-phase Biot media, taking into account inertial and viscous interactions of phases, are used for determination of the displacements of the basis. By the method of orthogonal polynomials a system of double integral equations of the contact problem (with a drained contact with coupling of rigid block and solid phase of twophase media) reduces to an infinite system of linear algebraic equations. At the numerical solution the dynamic and kinematic characteristics of motion of a block and distribution of contact stresses in the solid phase is evaluated. The relation of considered values from a permeability of a material of a base (half-plane) are investigated. |
