利用HEC-RAS软件计算山洪沟水面线

Water line calculation of torrents with the HEC-RAS software

本文以桦甸市某山洪沟为例,采用HEC-RAS软件,模拟分析了山洪沟在设计频率洪水下的水面线,为山洪沟治理工程的规模确定提供科学依据。计算结果表明,HEC-RAS软件在分析计算山区急流水面线时有较好的适用性,计算结果对工程有利,在山区河道及山洪沟治理工程中推荐使用该软件。

In this paper,taking a flash flood ditch in Huadian City as an example,using the HEC-RAS soft- ware simulates analysis of the frequency of flash floodsin the design of the ditch under the water hne for the torrents to determine the size of the ditch treatment project to provide a scientific basis.The results show that, HEC-RAS software analysis and calculation mountain rapids in the waterline has better applicability,the re- suits of the project favorably recommendeduse this software in the mountains,rivers and torrents ditch treat- ment projects.
