摘要
In this paper, a pile-bucket combined foundation for offshore wind turbines was proposed. It can be applied to 30 m water depth. And the software ABAQUS was used to simulate the bearing capacity of the foundation. The results have shown that the short piles can reduce the thickness of the subdivision boards and improve the anti-overturning ability of this foundation. The inclination of the flange can be reduced by 18.75% in the project. Then, under the multi-dimensional loading, the failure envelope line or surface of bearing capacity of this foundation was obtained through a large number of calculations. In practical engineering, safety and stability can be further evaluated according to the relative position's relationship between the force state and envelope line or surface. © 2021, Solar Energy Periodical Office Co., Ltd.
