Compressive Behavior of Helical Versus Pipe Pile Groups in Sandy Soil
https://orcid.org/http://orcid.org/0000-0002-6454-2613
This study investigates the performance of helical and straight pipe pile groups in sandy soils, focusing on their compressive axial load-bearing capacities through a series of small-scale model tests. The research highlights comparing two pile types, emphasizing the material efficiency and load-bearing advantages of helical piles. Both types of piles were tested under varying pile spacing and embedment depths. The results reveal that, for both pile types, the contribution of frictional load to the overall capacity is negligible, with most of the load-bearing capacity attributed to end-bearing. The study identified the optimal pile spacing and embedment depth for maximum load-bearing capacity to be 3.5 and eight times the diameter of the straight pipe pile, respectively. Despite straight pipe piles demonstrating up to 26% higher bearing capacity, they required twice the amount of steel compared to helical pile groups. In contrast, helical piles demonstrated up to 23% greater load-bearing capacity at embedment depths less than the optimal value.
