Interest in the problems of mechanics of contact interaction of rigid and elastic bodies determined by their wide applications in construction, seismology and other industries. Features of the pressure transmission in the contact zone are data of decisive importance when evaluating the risk of fracture of communication and foundation structures and their elements. In this article we've considered the problem of vibration of a stamp on the surface of the elastic layer containing a system of vertical rigid inclusions as a model of system base - foundation. The problem has been reduced to integral equations solvable by the method of fictitious absorption. We have obtained the characteristics of the stress-strain state of elastic foundation and analyzed stresses in the contact area of the stamp and base. The approach presented in this paper allows us to study the effects of vibration loads on the foundations of various types, including - pile foundations modeled by system of rigid vertical inclusions, when the fields of stresses and displacements generated by anchor pillars, by interacting with the main field in the elastic foundation, can either strengthen it or weaken.
