摘要
大坝是水工建筑物的重要组成部分,一旦发生溃坝,将对下游群众的生命及财产安全产生重大影响,因此,大坝安全问题备受关注。本文论述了溃坝问题的研究背景及实际意义,列举了多起由溃坝造成的巨大损失实例,从理论分析、水工模型试验、数值模拟三个方面论述了溃坝问题的研究方法,并结合国内外研究进展,介绍了大坝溃坝时溃口的发展过程、溃坝波演进情况以及溃坝风险的常用分析方法。
Dam is an important part of hydraulic structures,dam break has occurred from time to time in the past for half a century,and dam safety has attracted much attention.This paper discusses the research background and practical significance of dam break,enumerates several examples of huge losses caused by dam break,and discusses the main research methods of dam break from three aspects:theoretical analysis,hydraulic model test and numerical simulation.Combined with the research progress both domestic and abroad,the development process of dam break,the evolution of dam break wave and the common analysis methods of dam break risk are introduced respectively.
