摘　　要：河床地形观测是水闸变形监测的重要内容,其对水闸的安全运行评估具有至关重要的作用,常规的河床变形分析,以水深测量的数据为基础,通过南方cass等软件,绘制水下地形图及断面图作为最终成果,无法做到直观、准确、全面地了解河床变化。以芦潮港水闸附近河床变形观测为例,基于Surfer软件,以等值线渲染图、典型剖面图、冲淤分析图3种分析手段相结合,详细分析了该水闸两期的河床变形情况,并对不同分析手段进行了优劣性总结,对类似的水下地形监测具有很好的借鉴意义。The observation of riverbed topography is an important content of sluice deformation monitoring,which plays a vital role in safe operation evaluation of sluice.The conventional analysis of riverbed deformation,based on the data of water depth measurement,is carried out through the software of CASS,etc.,as the final result,the underwater topographic map and cross section map can not be drawn directly,accurately and completely to understand the change of riverbed,in this paper,the deformation of riverbed in two periods is analyzed in detail by using three analysis methods:Contour rendering,typical section drawing and erosion-deposition analysis drawing,and the advantages and disadvantages of different analysis methods are summarized,it can be used for reference for similar underwater terrain monitoring.
