导管架吸力筒基础是近年来兴起的一种新型的海上风电基础,目前对其承载特性的研究相对较少。针对四筒导管架海上风力机基础,通过建立不同筒间距的四筒导管架基础有限元模型,研究了筒间距对导管架基础在砂土中极限承载力的影响。研究发现：导管架基础的竖向承载力受筒间距变化的影响不大,而极限水平、抗弯以及抗扭承载力随筒间距的增大而呈现明显的增加趋势。
Abstract
Suction bucket jacket is a new type foundation for offshore wind turbines that has emerged in recent years. However, there are relatively few studies on its load-bearing characteristics. In this paper, a tetrapod suction bucket jacket for offshore wind turbine is studied. The influence of the bucket spacing on the ultimate bearing capacity of the tetrapod suction bucket jacket in sand is studied by establishing finite element models of the tetrapod suction bucket jackets with different bucket spacing. It is found that the vertical bearing capacity of the tetrapod suction bucket jacket is not greatly affected by the bucket spacing, while the ultimate bearing capacity of horizontal, bending moment and torque show a significant increasing trend with the increase of the bucket spacing.
