摘要
海底常规管线的探测已有很多成功实践经验,但是对于海底深埋管线(埋深>5 m)的探测,目前还处于摸索探讨阶段。本文详细介绍了采用高精度磁法探测上海某保滩工程中两根深埋钢筋混凝土引水管的实例,包括工作原理、方法技术、应用效果等。经钻探验证,高精度磁法能准确的探测出海底深埋钢筋混凝土管线,为同类工程提供技术参考。
There were many successful examples about routine submarine pipelines detection, but the detection of embedded submarine pipelines（embedded depth〉5 m） was at the beginning. Based on Shanghai beach protection project in which high-precision magnetic method was adopted to detect two embedded RC diversion pipes, an introduction was given to the principle, method, techniques and application effect etc. It was proved by borehole data that the embedded submarine RC pipeline could be detected accurately by using high-precision magnetic method, which would provide a reference for similar projects.
