摘　　要：汛期前后那板水库库势会发生较大的变化,边坡易发生崩岸险情和库床淤积,水库管理部门为关注水库变化,必须对水库进行监测。传统水库监测方式较为单一,如单波束测量等,难以达到较高的测深精度,处理效率较低。为更好地对水库进行管理,使用测深系统对水库进行水下地形图测量,测量采集大面积水库水下点云,测量精确数据,对水库的水下地形、淤积、无遗漏使用CAD描绘出来,并对各种比例尺的水下地形图,三维建模,固定剖面图和冲积情况进行分析。通过监测为水库管理提供大量的基础资料,分析结果能全面反映水库地形变化规律和趋势,提高水库管理的技术和水平。Before and after the flood season,the potential of Naban Reservoir will change greatly,and the slope is prone to collapse and siltation of the reservoir bed,so the reservoir management department must monitor the chang⁃es in the reservoir.It is difficult to achieve high bathymetry accuracy and the processing efficiency is low by relative⁃ly single traditional reservoir monitoring methods such as single-beam measurement.In order to better manage the reservoir,bathymetry system is used to survey the underwater topographic map for the reservoir,the underwater point cloud of a large area of the reservoir is measured and collected.Based on the accurate measuring data,the un⁃derwater topography and siltation of the reservoir are depicted without omission by use of CAD.Analysis is made on the underwater topographic map,three-dimensional modeling,fixed profile and alluvial situation of various scales.The monitoring provides a large amount of basic data for reservoir management,and the results of analysis can fully reflect the law and trend of reservoir topographic changes,which improve the technology and level of reservoir man⁃agement.
