    Abstract. The study of the bearing capacity and settlement of a single pile is quite an urgent task that many scientists have been engaged in, whose works present theoretical and numerical studies performed in various software complexes. In this work, the problem of the interaction of a long and incompressible pile with the surrounding and underlying soils in elastic and elastic-viscous formulations is considered in order to determine the values of stabilized and unstabilized (long-term) settlements, as well as the long-term bearing capacity of a single pile. The course of solving the tasks, as well as the basic formulas for calculating the settlement and bearing capacity of a single pile in elastic and elastic-viscous formulations is presented. To describe the rheological properties of soils under shear, the A. Z. Ter-Martirosyan rheological model was used as a calculation model, which makes it possible to describing all three main types of rheological curves: creep, stress relaxation and kinematic shear. Based on the studies performed, it was established that the stabilized settlement of the single pile directly depends on its geometric parameters and on the shear modulus of the soil surrounding the pile, and the long-term settlement of the single pile depends on the time-varying average viscosity of the soil around the pile.
    Key words: settlement, long-term bearing capacity, single pile, surrounding and underlying soils.
