    Abstract. The sediment of a single foundation transmitting static and dynamic harmonic pressure to the base is considered. The aim of the study is to obtain a new analytical solution that makes it possible to describe the deformation process over time, taking into account the rheological properties of sandy soil under the action of vibration, which depend on the intensity values of tangential and average stresses. The dependence of the viscosity coefficient of sandy soil on the level of static stresses and the intensity of vibrations, as well as the attenuation of vibration creep over time, were taken according to the previously obtained dependencies of Ter-Martirosyan A. Z. and Sobolev E. S. It was found that the sediment of a single foundation, to which vertical static and dynamic loads are transmitted, increases with an increase in its static and dynamic components, while A more significant contribution to the development of precipitation is made by the dynamic component formed by a viscoplastic shift of the type of bilateral discharge. The established general analytical dependences are consistent with the results of laboratory and field experiments performed by previous researchers, and can be used to predict the precipitation of a foundation on a non-water-saturated sandy base, which is a source of mechanical vibrations.
    Keywords: dynamic sedimentation of the foundation, sandy non-saturated base, vibrations of the base, dynamic cyclic load, vibration creep and viscosity of sandy soil, tangential stresses
