摘要
针对工程船舶常用的大抓力锚,考虑拖锚啮土深度和影响范围,确定海底电缆的最佳埋设深度。采用模型试验和数值模拟的方法分析拖锚过程中船锚的啮土轨迹;基于室内模型试验结果并结合船锚尺寸,提出船锚啮土深度与影响范围的理论计算方法。理论计算结果和数值分析结果与模型试验实测数据吻合良好,验证了理论算法和数值模拟方法的可靠性。
The meshing depth and the suffering area of dragging high holding power anchor were researched. The theoretical formula of anchor meshing depth and suffering area was established based on the model test. The numerical simulation was carried out to study the motion locus of dragging anchor. The field test was carried out to study the meshing depth of dragging anchor.The accuracy of the theoretical formula and the numerical simulation has been validated through field test whose results was in accordance with theoretical analysis.
