摘要

该文针对海上风电吸力式桩-桶复合基础开展离心模型实验与数值模拟分析

研究桶直径、桶壁长度、吸力桩直径、吸力桩桩长对基础单向承载性能与复合承载性能影响规律

结果表明：桶径的增加对提高承载性能最为显著

桩长的增加对提高基础整体水平向承载性能显著;V-H包络线形状不受桶长、桩径、桩长的影响

但包络线大小会随桶长、桩径、桩长的增大呈现外扩趋势

其中

桶径对包络线的影响最显著。

Abstract

By adding suction piles

the bucket size can be reduced

which is convenient for transportation and installation. In this paper

centrifugal model experiment and numerical simulation analysis were carried out for the suction pile-bucket composite foundation

and the influence rules of bucket diameter

bucket wall height

suction pile diameter and suction pile length on the bearing capacity performance were studied. The results showed that increasing bucket diameter the significantly improves the bearing performanee

while increaseing pile length enchanees the horizontal bearing performance. The shape of the envelope is not affected by bucket length

pile diameter and pile length

but the size of the envelope will expand outward with the increase of bucket length

pile diameter and pile length

and the influence of bucket diameter on the envelope is the most significant.
