摘　　要：海底管线路由探测对航道疏浚施工具有重要意义,而传统的探测技术手段单一,效率较低,无法确定掩埋段信息。为提高海底管线探测结果精度及作业效率,依托宁波舟山港条帚门航道扩建工程项目,综合利用侧扫声呐、浅剖及海洋磁探对工程区域海底管线进行探测:利用侧扫声呐成果作为裸露段海底管线探测结果的基本支撑,浅剖埋深结果与磁探反演埋深结果相互印证,共同提高了海底管线判别的准确性。工程应用结果表明,三种探测技术手段在海底管线探测方面的联合应用成果可靠,探测精度和作业效率显著提升,且具有较好的适用性,在类似项目中具有较好的参考和推广作用。Submarine pipeline route detection is of great significance for waterway dredging construction,while the traditional detection techniques have many problems,such as single technical means,low efficiency,unable to determine the buried section information and so on.In order to improve the accuracy of submarine pipeline detection results and operational efficiency,relying on Ningbo-Zhoushan port Tiaozhoumen waterway expansion project,comprehensively uses the side-scan sonar,sub-bottom profiler and marine magnetic detection technology to detect the submarine pipeline in the engineering area.The side-scan sonar results are used as the base data support of the submarine pipeline in the exposed section,and the sub bottom profiler buried depth results and the magnetic detection inversion buried depth results confirm each other,which jointly improves the accuracy of submarine pipeline discrimination.The engineering application results show that the joint application of the three detection techniques in submarine pipeline detection is reliable,with significantly improved detection accuracy and operational efficiency,and good applicability.It has a good reference and promotion role in similar projects.
