摘　　要：基于含沙量沿垂线分布出“拐点”的规律和探测沿垂线方向含沙浑水电阻率的物理方法 ,根据多年研究基础 ,利用泥沙、机械、电子、计算机等多学科综合技术 ,研制开发了河工模型实时浑水地形自动量测系统。本系统具有适应能力强、测量准确、实时性强、远程控制、数据在线处理等特点 ,解决了多年困扰黄河动床模型水下地形实时测量的特殊问题 。The real time automatic survey system in muddy water topography of river model is developed based on the laws of sediment concentration distributed along the vertical line and formed point of inflexion, the physical method of detecting muddy water resistivity along the vertical line and utilize multi-disciplinary comprehensive technology of sediment, machinery, electron and computer based on many years study. The system has the characteristics of strong adaptability, accurate survey, good for real-time, remote control and data on-line processing. It has solved the special issues of in water topography real-time survey of the Yellow River movable bed model that has been puzzled for years and provided scientific basis for hydraulic engineering design.
