摘　　要：以三维可视化的形式动态和形象模拟汀溪水库堤坝不同程度溃决情况下的洪水淹没演进过程。通过Sketch Up和Google Earth构建真实三维场景,在Real Flow中进行堤坝溃决模拟和洪水淹没模拟,使得人们能够预先获知洪水的淹没范围和水深的分布情况,较直观地预报洪水演进行为。对于制定抢险措施和群众紧急撤离路线、优化防洪抢险物资配置和动态评估洪灾损失等具有非常重要的价值,有利于挽救了人民的生命财产和减少洪涝灾害损失。This research proposes a three-dimensions dynamic and visual flood evolution imulation of Tingxi reser- voir in varying degrees of dam outburst. We can know the spread scope and depth of flood in advance by building true three-dimensions scene based on SketchUp and Google Earth, and imulating dam outburst and flood inundation based on RealFlow. That brings about an intuitive forecast about flood inundation, which is of great significant for leaders to formulate emergency measures and the emergency evacuation routes for crowd, optimize the flood preven- tion emergency commodity and the equipment, assess the flood losses dynamically so that brings about saving people life and property and reducing flood disaster losses.
