摘　　要：使用最新的HEC-RAS(6.1)软件进行溃坝洪水模拟分析,详细介绍了软件在溃坝洪水过程中地形生成、水库建模、参数输入、边界条件生成、计算以及后处理等操作流程。计算结果得到相应地区的淹没水深图和水深过程线,进而得出溃坝的影响区域,为决策部门提供相关的参考依据,研究方法可为今后类似溃坝洪水模拟研究提供参考。In this paper,HEC-RAS software is used for dam-break flood simulation analysis,using the latest HEC-RAS 6.1,the operation flow of the software in the process of dam-break flood,such as terrain generation,reservoir modeling,parameter input,boundary condition generation,calculation and post-treatment,is introduced in detail.The result of calculation can get the submerged water depth map and water depth process line of the corresponding area,and then get the influence area of dam break,and provide the relevant reference for the decision-making department,the research method can provide reference for similar dam-break flood simulation research in the future.
