摘　　要：与传统的测深仪相比,多波束测深技术采用条带式测量,可对水底进行全覆盖扫测,获取高密度点云数据,实现水底地形的精确三维表达。而无人船测量系统具有自主航行,灵活方便,可手动遥控相互切换等优点,搭载多波束测深系统在抛石护岸、河道整治和应急排险等方面得到广泛应用。该文通过使用集成化华微6号无人船搭载Norbit多波束测深系统对北江大堤西南段抛石前后测量的水底地形进行对比分析,结果能够直观准确地反映抛石前后的水底地形特征变化,并有效评价抛石护岸工程的施工质量。对今后类似的工程项目具有一定的借鉴意义。Compared with traditional bathymeters,multi beam bathymetry technology adopts strip measurement,which can perform full coverage scanning of the underwater,obtain high-density point cloud data,and achieve accurate three-dimensional representation of underwater terrain.The unmanned vessel measurement system has the advantages of autonomous navigation,flexibility and convenience,and can be manually and remotely switched to each other.Equipped with a multi beam bathymetric system,it has been widely used in riprap protection,river regulation,and emergency rescue.This article compares and analyzes the underwater terrain measured before and after the riprap of the southwest section of the Beijiang levee using the integrated Huawei 6 unmanned ship equipped with Norbit multi beam bathymetry system.The results can intuitively and accurately reflect the changes in underwater terrain characteristics before and after the riprap,and effectively evaluate the construction quality of the riprap revetment project.It has certain reference significance for similar engineering projects in the future.
