Abstract

With increasing demand and requirements for offshore wind turbines (OWTs) construction, research on the hybrid pile foundation is gaining increasing popularity. In this paper, a series of 1-g model tests are conducted to investigate the lateral behavior of monopile and hybrid pile foundations under one-way cyclic loading. The influence of pile stiffness, pile diameter for the hybrid foundation and hybrid foundation type on the lateral behavior of the structure is analyzed. To visualize particle movements during the loading process, several colored sand bands are arranged at ground surface around the structure. Continuous monitoring of sand surface during the loading process and excavation of sand sample reveal different particle migration patterns around different structures. Experimental results verify the superiority of hybrid foundation in resisting lateral loads and reducing accumulated lateral displacement. Based on the coupled discrete-continuum modelling of cyclic load tests, the deformation pattern of monopile and hybrid structure and the particle displacement contour at different sections are provided. The numerical results further point out the potential influence of the soil plug on the lateral capacity of the hybrid pile foundation, which could be the focus of future research.
