Calculation scheme of solid multi-layered base of the embedded foundation is offered for description of system vibration “foundation is a multi-layered base”. It is shown that in this case consideration of apparent mass of the solid multi-layered base, as well as foundation side surface friction leads to non-periodical (non-harmonic) damped vibration of the foundation. Different contact models including elastic, non-linear and rheological ones with regard to strengthening throughout the time are considered as for calculation for solution of problem of “system” vibration. It is shown that consideration of soil strengthening and side surface friction of the embedded foundation greatly influence the intensity of vibration damping throughout the time.
