海缆路由区船锚贯入量的研究分析

Research and analysis of anchor penetration on submarine cables route area

分析了海底光缆面临的锚害威胁,论证了锚害是造成海底光缆损坏最直接的原因。介绍了船锚对海底光缆的两种损害形式:撞击和拖拽。对这两种形式的过程进行了理论分析,从而概括了影响船锚贯入深度的主要因素,并提出用ABAQUS有限元软件分析船锚贯入深度的方法。

This paper analyzes the facing threats of anchor damage to submarine cables, proves the anchordamage is the most direct cause of the submarine cables damage. It introduces two kinds of damage modes ofanchor to submarine cables： striking and dragging. After that, the paper analyzes the process of anchor anddrag anchor, summarizes the main factors affecting the penetration of anchor, and proposes that usingABAQUS finite element software analyze the anchor penetration depth.
