Traditional monopile foundations cannot support the greater lateral loads and horizontal displacement needs required by offshore wind turbines due to their increasingly large size. Popularity has increased for a recently created hybrid pile foundation that combines a traditional monopile with a wide-shallow bucket. In this paper, 1-g model tests in soft clay are used to analyze the lateral behavior of hybrid pile foundation under static load. As a standard, the monopile with the same pile diameter and embedded length is employed. According to the experiment’s findings, the pile-bucket hybrid foundation’s lateral ultimate bearing capacity is more than 70% higher and its initial stiffness is nearly twice as good as that of a monopile foundation under the same lateral load. In addition, this paper compares the pile displacement, pile bending moment, and p-y curve of monopile foundation and hybrid pile-bucket foundation.
