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。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.
