“…A study by Yang et al [22] examined the bearing capacity, settlement characteristics, and force characteristics of screw-shaft piles under different loading conditions using both experiments and simulations. Among other findings, they figured out that the side resistance of screw-shaft piles first shows a rise as the length of the threaded section grows, reaching a stable value at an ideal length of roughly 0.44-0.55 times the total length of the pile.…”

Helical piles became a popular foundation technique, and as a result of environmental restrictions, they have become increasingly widely used. However, due to the high cost of experimentation, the influence of the number of helices and their positions on the pile-bearing capacity has not been sufficiently studied. The present study performed compression and lateral load tests on helical piles of the same diameter but with one, two, and three round helices in known sandy soil. The results from the experiments are compared with those from numerical simulations that use the mesh-free RBF method and the Winkler–Fuss approach to model how the pile and ground interact. The results are generalized to suggest an engineering equation that can predict the best pile configuration in sandy soil.
