摘要
为了研究漂浮式海上风电吸力锚尺寸对于水平承载能力的影响,以ABAQUS有限元软件为平台,采用弹塑性本构模型建立吸力锚基础的三维有限元模型,开展吸力锚不同尺寸影响分析。结果表明:直径和高度的增加均会提高吸力锚的水平承载能力,且高度的增加对水平承载能力的提升更为明显。随着直径和高度的改变,系缆点的位置也需要进行相应的调整,当吸力锚直径与高度之比D/H>1时,需要相应地提高系缆点的位置以使其发生平动位移。直径的改变会影响锚壁的压力变化,而高度几乎不会影响锚壁压力的变化。研究成果应用到全球首座漂浮式风渔融合平台“国能共享号”示范工程中并可为相关工程设计提供参考。
In order to study the influence of floating offshore wind power suction anchor size on the horizontal bearing capacity,based on the ABAQUS finite element software,a three-dimensional finite element model of suction anchor foundation was established by using elastic-plastic constitutive model.The results show that the increase of diameter and height can improve the horizontal bearing capacity of suction anchor,and the increase of height is more obvious.With the change of diameter and height,the position of the mooring point also needs to be adjusted accordingly.When the ratio of suction anchor diameter to height D/H>1,the position of the mooring point needs to be increased correspondingly to make it move in translation.The change of diameter will affect the pressure change of the anchor wall,while the height has little effect on the pressure change of anchor wall.The research results are used in global first offshore floating wind power+aquaculture platform“Guoneng Gongxiang Hao”and can provide a reference for relevant project design.
