河床冲淤变化的CAD可视化分析及应用

CAD visual analytics and its application in channel erosion and siltation

河床冲淤变化是许多重大科研及水电工程项目中需重点分析的内容,而冲淤变化结果如何直观地表现出来,已成为科研人员日益关注的焦点。将河床冲淤DEM分析与CAD应用有机结合,综合多个GIS应用系统集成开发了一个河床冲淤分析应用模块。从应用模块的处理方法与分析流程等方面,深入介绍了河床冲淤变化在CAD中的可视化表现与应用方法。众多生产实践表明,利用DEM算法开发的该河床冲淤分析应用模块原理简单,效果显著,直观实用。可为河演分析及河道治理工作提供帮助。

Channel erosion and siltation is a hot spot in many key scientific researches and hydropower projects, and how to visually express its variation result gradually becomes the common concerns of the researchers. Combing the DEM analysis of channel erosion and siltation with CAD, and incorporating multiple GIS application systems, an application module for channel e-rosion and siltation analysis is developed. From the treatment method and analysis process of the module, the visual realization of channel erosion and siltation in CAD are introduced. Numerous production practices show that, the application module developed by DEM algorithms is proven to be simple, effective, intuitive and practical, which is helpful to river evolution analysis and channel regulation works.
