This article provides a method of compaction of the soil base by creating a sealing pressure inside the soil massif. Nowadays, in buildings reconstruction, which is accompanied an increase loads on the foundations, in constrained conditions of dense urban development, the question strengthening of bases of foundations is important. The proposed a method of compaction of soil base by creating a sealing pressure inside soil massif is applicable both for new construction and for reconstruction of any objects in dense urban development. It carried out a comparative analysis of results of experimental and theoretical studies of the bearing capacity of piles with different parameters of broadening and compacted zone obtained by the method of compaction of soil base by creating a sealing pressure inside soil massif. Numerical studies to determine the bearing capacity of piles were performed in axisymmetric formulation using Hardening-Soil model. The method of determination of changes bearing capacity of base in depending on the diameters of broadening and compacted zone was carried out on a specially designed stand is presented. The article presents the results of experimental and numerical studies of bearing capacity of bases foundation.
