摘　　要：针对单波束测深方法验收水下抛石工程结果不唯一的问题,在某水利枢纽泄水闸下游柔性海漫冲坑水下抛石项目中,采用Kongsberg EM2040C(双探头)多波束测深系统,对水下点云数据进行滤波处理,利用ArcGIS对抛石前后的地形数据进行建模计算,结果能够真实地反映水下抛石增厚值、抛石总方量、欠抛和超抛区域,为该项目的验收评价提供准确唯一的结果。应用成果对类似水下抛石验收评价项目具有一定的借鉴意义。Aiming at the problem that the result of underwater riprap project acceptance by single beam sounding method is not unique,this paper applied Kongsberg em2040c(double probe)multi beam sounding system to filter the underwater point cloud data,andbuilt the model and calculated the terrain data before and after riprap.The results could better reflect the thickening value of underwater riprap,the total volume of riprap,the area of under riprap and over riprap,and provided accurate and unique results for the acceptance evaluation of the project.The application results could provide a certain reference significance for similar underwater riprap acceptance evaluation projects.
