Abstract: This paper collected and reorganized the calculation results of dam-breach flow of some hydropower stations in the power industry, and summarized and analyzed the current status of dam-breach flow calculation from the aspects of calculation methods and breach shape. The results showed that there were some problems in dam-breach flood analysis, such as improper selection of calculation methods and random assumption of dam breach shape. The suggestions provided in this paper could be used as a reference for dam breach analysis and research in similar projects.

Key words: hydropower station, dam-break flow calculation, breach shape

摘要: 通过收集、整理电力行业部分水电站大坝溃坝洪水计算结果,从计算方法选择、溃口型式拟定等方面,总结分析了目前水电站大坝溃坝洪水计算的基本现状。结果表明,目前溃坝洪水分析主要存在计算方法选择、溃口型式拟定比较随意等问题,提出了改进完善的意见和建议,供参考。
