摘　　要：为有效降低涉水工程运行安全风险,健全长江水灾害监测预警体系,设计并研发了基于B/S架构的重要涉水工程河床监测预警分析平台,实现了涉水工程三维仿真建模、河床动态生成和可视化模拟展示,对河床冲淤分析、演变动画模拟、等高线变化分析、自定义断面分析、河道坡比计算、河床最深点统计预警分析等河床监测预警分析功能进行了模块化设计,并成功应用于南京大胜关长江大桥的河床监测。实践表明:此平台可快速、直观地分析涉水工程局部河床冲淤演变过程,并具有自动预警功能,为沿江重要涉水工程河床监测的科学管理、隐患排查、安全维护提供了技术支撑。In order to effectively reduce the operational safety risk of the wading projects and improve the monitoring and early warning system of the Yangtze River water disaster, a riverbed monitoring and early warning analysis platform for important wading projects based on B/S architecture was designed and developed.The three-dimensional simulation modeling of the wading project, dynamic generation of the riverbed and the visual simulation display were realized.The riverbed monitoring and early warning analysis functions such as riverbed erosion and deposition analysis, evolution animation simulation, contour line change analysis, custom section analysis, river slope ratio calculation, and riverbed deepest point statistical early warning analysis were modularly designed and successfully applied to the riverbed monitoring of Dashengguan Yangtze River Bridge in Nanjing City.The practices show that this platform can quickly and intuitively analyze the evolution process of local riverbed scouring and silting in wading projects, and has automatic warning function, which provides technical support for scientific management, hidden danger investigation and safety maintenance of riverbed monitoring in important wading projects along rivers.
