摘要
船锚造成的海缆故障非常普遍,船锚的钩挂是造成海底光缆故障的主要原因,对海底光缆的锚害研究迫在眉睫。首先建立了船锚钩挂海缆的有限元模型,进行了船锚钩挂海缆的仿真,然后通过分析海缆受到船锚钩挂后的变形和应变,研究了海缆各组成部分抗船锚钩挂的能力、船锚损害海底光缆的机理以及海缆结构与抗船锚钩之间的关系,得出了相关的结论。
The anchor-caused fault on the submarine optical fiber cable（SOFC） is a frequent occurrence.And drag-ging by anchor is the main cause.It is urgently needed to investigate the anchor-caused fault on SOFC.A finite ele-ment model was built to simulate the reaction between the anchor and SOFC.The capability of the individual cable el-ements against dragging by anchor,mechanism of the anchor-caused fault on SOFC and relationship between the cable construction and the anti-anchor capability were investigated by analysis of the stress and strain of the cable dragged by the anchor.Correlative conclusions were made.
