摘　　要：为了保障断密涧河(尹庄村段)治理工程的顺利实施,根据工程特性和流域水文特征,应用HEC-RAS水力模型,对设计洪水条件下的河道水面线进行了模拟分析。结果表明:HEC-RAS软件能够较好得模拟出设计河道水面线,并通过有关图表给出各涉河建筑物的阻水影响范围,其中改建的交通桥和现有彩虹桥需要采取一定的工程措施增加其过流能力,方可保证断密涧河的行洪安全。In order to carry out Duanmijian River（Yinzhuangcun） controlling projects scientifically and reasonably, this paper applied HEC-RAS to analyze river water surface curve under the created conditions, based on engineering characteristics and hydrological characteristics. Results show： HEC-RAS software could calculate the water surface line, and provide current-obstruction area of the hydraulic structures vividly. Duanmijian River flood safety can be ensured only if the recreation traffic bridge and existing Rainbow bridge discharge capacity will be increased by some engineering measures.
