摘要
介绍了HEC-RAS软件的功能,着重分析了面板坝的溃决过程,并对溃口处流量、水位的变化规律进行了初步归纳。通过对面板坝溃决过程的分析研究,提出了一种基于HEC-RAS软件面板坝一维溃决的溃口发展模拟方法。拟定了基于传统方法和此溃口方法对大桥水库进行溃坝模拟,得到两种方法下溃口处的水位流量过程数据,对模拟结果进行了对比。结果表明,此溃口模拟方法更适合于面板坝的溃决过程模拟。
This paper introduced the HEC-RAS software simply,analyzed the process of concrete-faced rock-fill dam,and concluded the chanfinf rules of the stafe and discharfe in the breach. Throufh the analysis of the process of concrete-faced rock-fill dam,this paper put forward an optimization method of simulatinf the concrete-faced rock-fill dam breakinf in a one-dimensional way based on the HEC-RAS software. There were two dam-breakinf simulation schemes of the Daqiao Reservoir,one was simulatinf in traditional method and the other was in the optimization method. By comparinf the results of two schemes and considerinf the breach stafe and discharfe of Gouhou Reservoir,it shows that this optimization method is more suitable for dam-breakinf simulation of the concrete-faced rock-fill dam.
