摘　　要：HEC-RAS具备简洁的操作界面,简单的模型设置方式,处理复杂河流及涉河建筑物的强大能力以及准确的模拟计算结果,在河道治理工程分析计算中应用广泛。以贵州省小黄泥河树嘎村段河道治理工程为例,利用HEC-RAS模型对研究区建立一维恒定流模型,进行多方案的分析计算,可为优化工程治理方案布置提供决策参考。计算结果表明,HEC-RAS模型模拟计算简便,水面线成果精度较高,可为中小河流治理方案设计和优化提供决策参考,满足贵州山区中小河流治理工程的精度要求。HEC-RAS is widely used in the analysis and calculation of river management engineering due to its simple operation interface,simple model setting,powerful ability to deal with complex rivers and river-related buildings,and accurate simulation results.Taking the Shuga Village section of Xiaohuangni River in Guizhou Province as an example,the HEC-RAS model is used to establish a one-dimensional constant flow model for the study area,and the multi-scheme analysis and calculation are carried out,which can provide decision-making reference for optimizing the layout of project management schemes.The results show that the HEC-RAS model is simple to simulate and has high precision of water surface line results,which can provide decision-making reference for the design and optimization of small and medium-sized river management scheme,and meet the precision requirements of small and medium-sized river management projects in mountainous areas of Guizhou.
