摘　　要：水电站作为重要的水工建筑物,其在长期水力作用和环境因素下,坝前很容易淤积泥沙、木头等大型垃圾,这对水电站大坝的安全造成了巨大隐患。拟使用多波束测深系统进行水电站坝前淤积的全覆盖三维水下地形图的测量并利用侧扫声呐测量技术印证上述地形图量测结果的合理性。多波束测深系统与侧扫声呐技术生成的三维水下地形图、水下二维影像能够客观真实地反映坝前淤积情况,为水电站坝前淤积清理提供可靠数据。Hydropower station is an important hydraulic structure.Under the long-term hydraulic effect and environmental factors,it is easy to deposit sediment,wood and other large garbage in front of the dam,which has caused great hidden danger to the safety of the dam.In this paper,a multi beam bathymetric system is used to measure the full coverage three-dimensional underwater topographic map of sedimentation in front of the dam of hydropower station,and the side scan sonar measurement technology is used to verify the rationality of the above topographic map measurement results.In this paper,the three-dimensional underwater topographic map and two-dimensional underwater image generated by the multi beam sounding system and side scan sonar technology can objectively and truly reflect the siltation in front of the dam,and provide reliable data for the clearing of siltation in front of the dam of hydropower station.
