Materials of soil, widespread at the Republic of Uzbekistan, have rheological properties (that is stress-strain relation that depends on time) [6, 7, 9]. Viscoelastic properties of soil (creeping and relaxation) appear to different degree under static and dynamic effects [9-12]. Necessity to account viscoelastic properties of soil is actual in the design and engineering of earth structures, earth dams particularly located in the zones with high seismic risk, where the structure is subjected to the intensive dynamic loads, especially in resonant and near-resonant modes of vibrations [13, 14]. At such modes of vibrations viscoelastic properties of a material due to dissipative (absorbing) properties damp undesirable vibrations of a structure.
