This paper deals with a description of the behavior of the two-phase soil layer (column) under periodic load. The soil layer (column) is fully saturated with single pore fluid and treated by the methods of continuum mechanics. Description of motion and deformation of soil is introduced as a system of equations consisting of governing dynamic consolidation equations based on Biot theory, selected constitutive and kinematic relations for small strains and rotation. The solution and results of simple one dimensional numerical analysis of the fully saturated layer under cyclic load are included. Also the so-called dynamic coefficient which shows amplification or attenuation of dynamic response is considered.
