摘　　要：倾斜荷载作用下吸力锚的承载力一直是漂浮式风机吸力锚基础设计的关键,为提供可靠的吸力锚承载力,基于有限元数值模拟软件ABAQUS,分析吸力锚不同系泊点位置与系泊角度对吸力锚倾斜抗拔力的影响。结果表明:吸力锚倾斜抗拔承载力随系泊角度增大而减小;吸力锚破坏模式随系泊点下移由前倾破坏转为平动再转为后倾破坏,锚身旋转点随系泊点深度增加先下移后上移;吸力锚倾斜抗拔承载力随系泊点深度的增加呈现先增大后减小,最佳系泊点为基础埋深0.6L~0.8L处。In order to provide a reliable bearing capacity of suction anchors,based on the finite element numerical simulation software ABAQUS,the influence of different mooring point positions and mooring angles of suction anchors on the tilt and pull-out resistance of suction anchors is analyzed.The results show that the uplift capacity of the suction anchor decreases with the increase of the mooring angle.The failure mode of the suction anchor changes from forward tilt failure to translational and then backward tilt with the downward movement of the mooring point,and the anchor rotation point moves first downward and then upward with the increase of the depth of the mooring point.The inclined uplift bearing capacity of the suction anchor increases first and then decreases with the increase of the depth of the mooring point,and the optimal mooring point is at the depth of 0.6L~0.8L.
