Proposals have been developed regarding the use of the optimal form of profiles for reinforcing soil-cement piles. An analysis of the parameters of the compositions for strengthening the subgrade and bases and foundations was carried out to determine the rheological, operational and physical-mechanical properties of mixtures for reinforcing soil-cement piles. The optimal composition and properties of soil cement components have been developed for strengthening the subgrade and bases and foundations. The analysis of the existing methods of strengthening the subgrade and bases and foundations was carried out. Mathematical modeling of the "subgrade or base and foundation - soil-cement piles" system was performed. The obtained regularities of the stress-strain state of the system "subgrade and foundation - soil-cement piles" during the variation of the deformation parameters of the elements of soil-cement piles.
