Theoretical modeling on the performance of offshore circular foundation installed on clay and subjected to combined horizontal-vertical load in the Niger Delta has been attempted. Analytical methods of Skempton, Brinch Hanson, and Vesic were used to evaluate concentric vertical loads on offshore piles. Horizontal forces, H were evaluated for varying wave heights on circular piles of 1.0 to 2.0 m diameters using available meteorological and oceanographic offshore records. The results revealed that sliding failure commenced when the ratio of vertical load to footing area and undrained shear strength, V/Asu assumed negative values (i.e. at H > 0.082 Asu). The maximum mean vertical load is 6.107 Asu, and to guide against the occurrence of bearing capacity failure by sliding, V > 0.75H for cases where the ratio of footing depth to breadth ratio is lesser than one, (D/B < 1.0) and V > 0.70H when footing depth to breadth ratio is greater than one (D/B > 1.0).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
