Study of performance of the raft foundation reinforced with piles






The article is devoted to the design methods for strengthening foundations with an account of the actual stress-strain behavior of bases and foundations. In the normative documents, there are no recommendations on the calculation for strengthening raft foundations reinforced with piles. Methods of strengthening of the foundation with piles proposed in the scientific literature do not take into account the actual stress-deformation condition of the strengthened foundation base. There was carried out a numerical study of the raft foundation and strengthening piles interaction. There are some regularities recommended for strengthening foundation design. A method of calculating the loads on the soil-cement piles at strengthening slab foundation taking into account the loads on the raft base before strengthening is proposed.
