摘要
为了解水库的泥沙淤积现状,采用RTK技术和数字测深技术,并使二者相配合实现同步测量,使其在大比例尺地形测量中得到成功应用,测绘质量和工作效率明显提高,测量成本显著降低。本文以黄河刘家峡水库坝前1∶200水下地形测量的生产实践为例,叙述了大比例尺水下地形测量实施过程和测量所取得的成果及体会,为今后的水库水下地形测量积累了经验。
To know the present situation of sediment deposition of reservoir,the synchronous measurement combined with RTK and digital sounding technique has applied successfully in large scale topographic survey.The quality and efficiency of survey work has obviously improvement and the cost is reduction.Taking the 1:200 topographic survey under water in front of the dam of Liujiaxia reservoir on Yellow river for an example,the paper describes the implementation process and achievement of the large scale topographic survey under water and accumulated experience for future.
