Numerical methods for calculating cells for determining the reduced modulus of deformation of a soil mass reinforced with vertical reinforced concrete elements based on the use of modern regulatory documentation, as well as numerical modeling methods, with further quantitative evaluation and comparison of the results obtained are considered. Shortcomings of the formula of SP 22.13330.2016 «Foundations of buildings and structures.Updated version of SNiP 2.02.01-83*» are revealed when comparing with the results of numerical modeling of soil cells reinforced with elements of increased rigidity. The existing formula for determining the reduced modulus of deformation is based on a number of assumptions and does not take into account the distinctive work of reinforced bases under load, the interaction of reinforcing elements both with each other and with the surrounding ground of the base. The rigidity of the reinforcing elements in the form of reinforced concrete piles in combination with the soil body overestimates the value of the reduced modulus of cell deformation, which is confirmed by field experiments and the results of numerical modeling.
