摘　　要：水下穿越管道在运行过程中,受到水流冲刷以及采沙的影响,管道覆土层逐年减薄,甚至出现暴露和悬空等不利情况,此时管道直接受到水流冲刷、砂石撞击、船锚及捕鱼工具撞击等多种因素的损伤破坏。本文结合电磁法理论与实际工程案例,采用先进的DEEP SEE系统开展水下穿越管道的检测应用研究,该系统能够实现水下管道与大埋深管道的检测,自动化程度高,误差小。During the operation of the underwater crossing pipeline,the layer of soil covering the pipeline is thinning year by year due to the impact of water flow scouring and sand mining,and even exposed and suspended.At this time,the pipeline is directly damaged by various factors such as water flow scouring,sand and stone impact,ship anchor and fishing tool impact.Combined with the theory of electromagnetic method and practical engineering cases,this paper adopts the advanced deep see system to carry out the detection application research of underwater crossing pipeline.The system can realize the detection of large buried depth of pipeline,with high degree of automation and small error.
