摘　　要：介绍了HEC-RAS的主要功能,针对柳川河的现状,利用该软件进行河道与交叉建筑物联合建模、洪水因子输入、流态选择。通过计算比对验证了软件建立桥梁模型的可靠性,通过分析结果数据中的水力要素,确定了河道防护措施,保障了河道行洪安全。The paper introduces the major function of Hec-Ras. In the light of Liuchuan River＇s current status, the Hec- Ras is used to model river and crossing structure, input flood factors and choose flow regime. Via the calculation and comparison, the reliability of bridge modeling by Hec-Ras is validated, based on the analysis of hydraulic elements in result files, the river＇ s protective measures is confirmed and the safety of the river is guaranteed during flood.

关 键 词：HEC—RAS建模 桥梁模型 过水能力 河道行洪 安全
