摘　　要：溃坝洪水会对下游地区的人民生命和财产安全造成重大威胁,对溃坝洪水进行模拟及风险评估对防灾减灾工作具有重要意义。本文以四川成都市紫坪铺水库为研究对象,在模拟溃坝洪水流量过程的基础上,采用二维水动力模型模拟了溃坝洪水演进过程,分析了全溃、半溃和三分之一溃工况下紫坪铺水库发生溃坝洪水后下游的淹没情况,同时绘制了不同溃坝洪水工况下的淹没水深图和洪水到达时间图,为区域水灾害风险预警提供科学有力的技术支撑。Dam break floods can pose significant threats to the lives and property of downstream communities,making the simulation and risk assessment of dam break floods critical for disaster prevention and mitigation efforts.This paper focuses on the Zipingpu Reservoir in Chengdu,Sichuan Province,and simulates the dam break flood flow process.Using a two-dimensional hydrodynamic model,the progression of the dam break flood is modeled.The study analyzes the inundation conditions downstream of the Zipingpu Reservoir under scenarios of full,half,and one-third breaks,and presents inundation depth maps and flood arrival time charts for these conditions.These simulations provide robust technical support for regional flood disaster risk warnings.
