The article considers innovative pile technologies that can significantly increase the load-bearing capacity of reinforced concrete piles by increasing the friction forces on the side surface of hanging piles. The authors developed designs of modular reinforced concrete piles for the perception of various combinations of external influences, and also studied the influence of the granulometric composition of the soil adjacent to the pile body on its load-bearing capacity. The study included dynamic tests of t-shaped and square piles, theoretical studies of the interaction of t-shaped piles with clay soil by mathematical modeling, and the selection of the composition and distribution of coarse-grained filler around the pile developed by the authors with “pockets” (cavities) during its driving. The developed innovative solutions allow increasing the angle of internal friction of the soil adjacent to the reinforced concrete pile, while increasing the load-bearing capacity.
