摘要
珊瑚礁地质是我国南海岛屿周边海域的典型特征.我国南海的珊瑚礁地质特殊,存在无法深埋海底电缆的问题.在各类复杂环境因素的作用下,裸露的海底电缆极易受到破坏.文章围绕施工、渔业活动和海生物附着等各类复杂因素对海底电缆安全性能造成的破坏进行了风险评估,分析了破坏机制.同时,结合珊瑚礁地质下的海底电缆铺设和运维实际情况提出了多项海底电缆防护措施,将为海底电缆在我国南海典型珊瑚礁地质条件下的可靠运行提供更多支撑,保障系统运行安全.
Abstract
Coral reef geology is a typical feature of the surrounding waters of the South China Sea islands.The coral reefs in the South China Sea have special geology,and there is a problem that submarine cables cannot be buried deep.Under the influence of various complex environmental factors,exposed submarine cables are extremely vulnerable to damage.In this paper,the risk assessment of the damage to the safety performance of submarine cables caused by various complex factors such as construction,fishery activities and marine biological attachment is carried out,and the failure mechanism is analyzed.At the same time,combined with the actual situation of submarine cable laying and operation and maintenance under coral reef geology,a number of submarine cable protection measures are proposed,which will provide more support for the reliable operation of submarine cables under typical coral reef geological conditions in the South China Sea and ensure the safe operation of the system.
