摘要
海缆大规模敷设后面临各种威胁,其中锚害是造成海缆损坏的首要原因。海缆故障查找难度大、修复时间长,如何快速对损毁海缆进行断点定位是急需解决的技术问题。传统的磁力探测手段效率低且连续性差,针对传统物探方法很难对海缆断点快速定位的难题,提出了一种利用光时域反射法确定海缆断点大致区域,再使用低频合成孔径声呐与侧扫声呐同步探测并结合超短基线进行水下定位的快速获得海缆断点精确位置的新方法并结合福建某风场采集的实测数据进行分析比对,得出该方法获得的海缆断点位置准确可靠,误差范围在1 m以内。
Submarine cable is faced with various threats after large-scale laying,among which anchor damage is the primary cause of submarine cable damage.It is difficult to find submarine cable fault and takes a long time to repair.How to locate the breakpoint of damaged submarine cable quickly is an urgent technical problem.Due to the low efficiency and poor continuity of traditional magnetic detection methods,it is difficult for traditional geophysical methods to quickly locate the breakpoint of submarine cable.In this paper,an optical time-domain reflectometry method is proposed to determine the approximate area of submarine cable breakpoint.Then,a new method of fast accurate location of submarine cable break point is obtained by using low-frequency synthetic aperture sonar and side-scan sonar synchronous detection combined with ultra-short baseline for underwater positioning,and combined with the measured data collected from a wind field in Fujian Province for analysis and comparison,it is concluded that the submarine cable break point location obtained by this method is accurate and reliable,and the error range is less than 1 m.
