摘要
根据H EC-RAS软件的基本原理,以宜昌市鸣翠谷景区涉河工程防洪评价中水面线的计算为例,采用HEC-RAS软件中的一维水面线计算模型,模拟5%设计洪水频率下工程前后的河道水面线情况。计算结果表明,HEC-RAS软件在进行河道水面线的分析时方便实用,工程适用性很好,可作为防洪工程决策的参考。
According to the basic principles of the HEC-RAS software,taking the calculation of the water surface line in the flood control evaluation of the Mingcuigu scenic spot in Yichang City as an example,the one-dimensional water surface line calculation model in the HEC-RAS software is used to simulate the 5%design flood frequency river water surface conditions before and after the project.The calculation results show that HEC-RAS software is convenient and practical in the analysis of river surface lines and has good engineering applicability,and can be used as a reference for flood control engineering decision making.
