摘要: 水利工程溃堰洪水演进分析对工程设计与灾害预警有重要意义。基于Virtual Reality Platform(VRP)平台,利用图形图像处理方式直观地模拟洪水演进过程,系统全面地分析洪水要素在时间与空间上的相互关系。融合多种数字处理技术进行数据可视化,建立洪水水力要素的时序变化与图形之间的映射关系,表现河道溃堰洪水水位、水深等水力要素的演变过程。实例说明VRP可模拟围堰溃堰洪水演进全过程,实现动态分析与用户交互,表明基于VRP的溃堰洪水演进动态4D可视化对洪水风险整体分析具有独特优势。

Abstract: Analysis on the routing of flood caused by cofferdam failure is of great importance for water dam project design and disaster warning. Based on VRP (Virtual Reality Platform), a method is presented to intuitively demonstrate the flood routing on computer with graphic and image processing techniques for a systematic and comprehensive analysis of the interrelation of the flood elements over time and space. This method integrates several digital processing techniques to visualize the data. The evolution of hydraulic elements, inclusive of water level and water depth in the river channel over time, is displayed by establishing the mapping relation between sequential variations of hydraulic elements and graphics. A case study shows that the method could simulate the routing of cofferdam failure flood and achieve dynamic analysis and user interaction. The results indicate that the visualization of flood routing caused by cofferdam failure based on VRP is of a distinct advantage in the integrity analysis of flood risk.
