| 摘 要： | 针对一种四筒导管架海上风机基础,基于有限元数值分析,通过建立砂土中不同筒径和筒高的四筒导管架基础有限元模型,研究砂土中单调弯矩荷载的作用下,筒径与筒高对导管架基础抗弯承载力的影响。分析结果表明:四筒导管架风机基础的抗弯承载力随着筒高或筒径的增加呈明显的增长趋势,相比于筒径的增加,筒高的增加对提高基础抗弯承载力更为有效;在极限弯矩荷载的作用下,基础旋转中心水平向位置受筒高的影响较大,但竖向位置受筒高和筒径的影响很小。

| Abstract: | A series of finite element models were established for a four-bucket jacket offshore turbine foundation with different bucket diameters and skirt lengths to study the effect of skirt height and bucket diameter on its ultimate moment bearing capacity under the action of monotonic moment loading in sandy soil. The results show that the moment bearing capacity increases obviously with the increase of skirt height or bucket diameter. Compared with the increase of bucket diameter, the increase of skirt length is more effective to improve the bearing capacity. Under the action of ultimate moment load, the horizontal relative position of the foundation rotation center is significantly affected by the skirt length, but the vertical relative position is little affected by the skirt length and bucket diameter. |
