Construction of transport infrastructure facilities on weak subgrades requires special soil improvement measures. One of the advanced methods for deep subgrade soil compaction is known to be Full Displacement Piles (FDP). The purpose of this paper is to establish dependencies of subgrade deformation properties of a soil body reinforced with full displacement piles on reinforcement parameters and soil conditions. Using numerical simulation methods, the authors identified reinforcement parameters and initial soil indicators that have a significant effect on change in the deformation modulus of the reinforced body in the considered boundary conditions. Results of field experimental studies confirmed the reliability of the newly established relationships and regularities.
