摘    要:长江水质浑浊、流速较大,传统水下建筑物现状检查方法如潜水摸查和水下视频录像不再适用,而利用多波束测深技术进行全覆盖扫测,并对水下高精度点云数据三维建模,能够实现水下建筑物现状可视化和缺陷定量分析。针对长江某水厂取水管现状检查工程,利用Kongsberg EM2040C(双探头)多波束测深系统,通过设计测线、选择合适的波速角和发射角,利用自适应滤波算法对获取的高精度、高分辨率水下点云数据进行精细处理,结果能准确反映取水管破残现状和破损位置,为该水厂取水口修复项目提供了可靠的基础数据资料。应用成果对类似工程的现状检查和加固修复具有一定的借鉴意义。

关 键 词:多波束测深技术  水下检查  自适应滤波  点云数据  缺陷定量分析  三维建模

Abstract:Traditional underwater inspection methods like manual diving inspection and underwater video recording are no longer applicable to the underwater inspection in the Yangtze River due to large flow rate and muddy water. In this research we adopted multi-beam sounding technique to perform full-coverage scanning to obtain high-precision point cloud data. Through 3D modeling, we visualized the conditions of underwater buildings and quantitatively analyzed the defects of water intake pipes of a water plant in the Yangtze River as a case study. Using the Kongsberg EM2040C (dual-probe) multi-beam sounding system, we designed the measurement route and chose reasonable wave speed and launch angle, and precisely processed the obtained high-precision and high-resolution underwater point cloud data using adaptive clip. The result accurately reflects the status of broken water pipes and broken locations, and provides reliable basic data for the water plant’s intake restoration project. The achievements can also be taken as reference for the condition check and reinforcement and restoration of similar projects.
Keywords:multi-beam sounding technology  underwater inspection  adaptive filter  point cloud data  quantitative analysis of defects  3D modeling
