海底光缆(简称海缆)敷设环境复杂,面临着多种威胁。为此,对海缆安全运行危害最大的船锚造成海缆故障的类型、后果,船锚对海缆的损伤力,以及对船锚威胁的防护措施进行了详细的阐述,指出为了维护海缆的正常运行,确保通信畅通,应依据各水深及人类活动的情况,选择合适的埋设方式和埋设深度,避免海缆因锚害造成巨大的经济损失。 Submarine cable (referred to as submarine cable) laying complex environment, facing a variety of threats. For this reason, the types and consequences of submarine cable faults, which are the most damaging to the safe operation of submarine cables, are described in detail. The damage of submarine cables to anchors and the protective measures against the threat of anchors are described in detail. Normal operation of the submarine cable to ensure smooth communication should be based on the depth of water and human activities, the choice of the appropriate burial depth and embedding, to avoid the anchor cable caused huge economic losses.
