摘要
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 installation of more and more submarine optical fiber cables （SOFC）, the maintenance of SOFC becomes more crucial. The faults of SOFC caused by anchor account for about 80% of the total faults of SOFC, so they have become the important point of SOFC maintenance. In order to keep perfect communications it is necessary to study the faults caused by anchor. By establishing finite-element models of SOFCs and the simulation of anchor hooking SOFC, the anti-hooking capability of the components of SOFC is analyzed. In addition the relationship between SOFC＇s structure and anti-hooking capability is studies through comparing the strain of various structures of SOFC, and associated conclusions are made.
