【摘要】 本文通过堰塞坝漫顶溃坝模拟实验,将堰塞坝溃坝归纳概括为初始溃口形成、溃口发展、最终稳定三个阶段。在其他参数相同的情况下,通过对3组实验流量变化的比较,研究了坝体高度、长度与洪峰流量、洪峰来临时间、洪峰持续过程的相互关系,并研究了溃口形状特点,对相关工程应用有一定借鉴意义。更多还原

【Abstract】 In the paper,weir dam breaks are concluded into three stages of initial dam break formation,dam development and ultimate stability through weir dam overflow dam break simulation experiment. Under the condition that other parameters are the same. Experiment flow changes of the three groups are compared for studying mutual relationship between dam height and length with flood peak flow, flood peak coming time and flood peak duration, and the characteristics of break shapes are studied,thereby providing certain reference significance for related projects.更多还原
