堰塞坝溃决洪水的三维视景模拟关键技术
Key Technologies of Three-Dimension Visual Simulation on Outburst Flood of Barrier Dam
摘要
Abstract
China is an earthquake-prone area. Once the earthquake-induced barrier dam outburst,it will cause a devastating effect on the downstream cities and protected areas. Because of the complexity and unrepeatable of the barrier dam,numerical simulation and physical model experiment can not fully show its characteristics. While,three dimension visual simulation can accurately provide the dynamic evolu-tion process of the flood routing in the virtual environment and has significant advantages. This paper mainly expounded the key technologies of three-dimension visual simulation on outburst flood of barrier. Based on the dam flood calculation model and the coupling between the three dimension visual simulation,three dimension analysis and simulation were carried out on the dam flood,and the three-dimension visual simu-lation of the dam flood simulation and application were implemented. Compared with the traditional one-dimensional or two-dimensional hy-drodynamic calculation and display,three-dimension visual simulation was more accurate and intuitive,which provided an effective approach for research outburst flood of barrier dam,and reference basis for early response and reducing the losses caused by barrier dam outburst.关键词
