摘要:
堤防抛石护岸工程具有一定的隐蔽性,通常基于抛石前后的水底地形变化评估其抛投质量与实施效果。多波束测深系统获取的水底地形点云数据,实现了水底地形的精细三维表达,其包含的许多隐式信息可以用于水利工程的质量检测与效果评估。本文从点云的几何特征出发,将曲率特征与粗糙度特征用于抛石前后水底地形的变化分析,分析其用于抛石工程检测中的可行性。实验表明:将点云几何特征用于堤防抛石护岸工程的质量检测,不仅可以直观地查看抛石前后的水底地形特征变化,且可以快速地定位欠抛或漏抛区域,较传统的方法具有明显的优势。
Abstract:
The riprap revetment of embankment has a certain concealment, which is usually based on the underwater topographic changes before and after the riprap to evaluate its throwing quality and implementation effect. The underwater terrain point cloud data obtained by the multi-beam sounding system realized the fine three-dimensional expression of the underwater terrain, which contained a lot of implicit information could be used for quality inspection and effect evaluation of water conservancy projects. Starting from the geometric features of point cloud, curvature characteristics and roughness characteristics were used to analyze the changes of underwater topography before and after riprap, and the feasibility of applying them on the detection of riprap engineering. The experimental results showed that the geometric features of point cloud used in the quality inspection of riprap revetment project of embankment could not only visually see the changes of underwater topographic features before and after riprap, but also could quickly locate the under-throwing or leaking areas, which had obvious advantages over traditional methods.
