多波束测深技术在高坝洲坝前淤积测量中的应用

摘要

介绍在高坝洲坝前淤积测量中引进的水下多波束测深系统测量方法，该方法具有范围大、速度快、精度高、记录数字化以及成图自动化等优点，能精确、快速测定沿航线一定宽度内水下目标的大小、形状、最高点和最低点，较可靠地描绘出水下地形的精细特征，高坝洲坝前水下三维地形扫测结果表明，该方法能直观、准确地反映坝前淤积情况。%The underwater multibeam bathymetric technique applied in reservoir sediment survey in Gaobazhou power station is introduced , which is of advantages of wide range , high speed , great precision , digital recording and automatic mapping, etc.It is capable to determine the size , shape, and the highest and lowest points of underwater target within a certain width along the survey route accurately and quickly , thus the delicate characteristics of the underwater terrain can be discovered .Three-dimensional underwater topographic survey results of the reservoir in Gaobazhou power station demonstrate that the multibeam bathymetric technique can reflect the siltation situation accurately .
