随着海底光缆敷设数量的增加,海底光缆的维护工作越来越紧迫。因船锚造成的海底光缆故障达到了海底光缆故障总数的80%以上,它已经成为海底光缆维护工作的重点。为了保证海底光缆的通信畅通,对海底光缆锚害的研究非常有必要。通过建立海底光缆的有限元模型,并进行船锚钩挂海底光缆的仿真,分析了海底光缆各组成部分的抗船锚钩挂能力。通过对比各类型海底光缆受到的应变,研究了海底光缆结构与抗船锚钩挂能力之间的关系,并得出了相关的结论。
With the increase in the number of submarine cable laying, submarine cable maintenance work more and more urgent. The submarine cable failure caused by the anchor has reached more than 80% of the total number of submarine cable faults, and it has become the focus of submarine optical cable maintenance work. In order to ensure the smooth communication of the submarine cable, the research on the submarine cable anchoring is very necessary. By building the finite element model of the submarine cable and simulating the submarine cable with anchor hook, the anti-anchoring ability of each component of the submarine cable is analyzed. By comparing the strain of various types of submarine cables, the relationship between submarine cable structure and anti-anchoring ability is studied, and the related conclusions are drawn.
