摘要 

海底电缆的探测和识别技术是海底电缆维护与建设中非常重要的研究内容。海底电缆布设于海底,在通电情况下产生电场和磁场,符合可控源电磁法探测理论。本文采用频率域可控源电磁法2.5维高精度有限元数值模拟算法对海底电缆模型进行模拟与分析研究,以水平地形和起伏地形海底电缆模型为基础,重点对海水层厚度和海底界面两种参数变化前后电磁场分布特征进行了模拟与分析。数值算例表明:磁场分量Hy对于海水层厚度非常敏感,厚度变化0.2 m时,变化前后Hy偏差可达5%,从而论证了采用可控源电磁法理论对于海底电缆的探测和识别可行。

Abstract

The detection and identification technology in the maintenance and construction of submarine cables has become a very important research content. In this paper, a 2.5-dimensional high-precision finite element numerical simulation algorithm of the frequency domain CSEM method was used to simulate and analyze the submarine cable model. Based on the horizontal terrain and undulating terrain submarine cable models, this study focused on the simulation and analysis of the characteristics of the electromagnetic field distribution with the changing of seawater layer thickness and the submarine interface. Numerical examples show that the magnetic field component Hy is very sensitive to the thickness of the seawater layer. When the thickness is changed by 0.2m, the Hy error anomaly amplitude can reach 5%, thus demonstrating that the CSEM theory is feasible for detection and identification of submarine cables.
