Abstract

With the rapid development of offshore wind energy, the seismic stability of foundation structures is a concern, especially if the soil is sandy soil that is susceptible to liquefaction. One of the commonly used foundation structures for offshore wind is the bucket foundation. A group of centrifuge tests were performed to study the seismic behavior of the foundation. Acceleration, pore water pressure, settlement, and lateral displacement were recorded to analyze the seismic response of both the upper structure and foundation. The influences of design parameters such as size of the foundation, depth of penetration in the ground, compartments within the foundation were evaluated. The experimental data show that the bucket foundation is capable of resisting failure under seismic event.
