摘要: 分析了泥沙起动流速的研究现状,对众多起动流速公式进行分析、评述,根据实测实验数据分析指出复合坡 起动流速较平坡起动流速的差别,分析其原因,对工程实际或科研中起动流速的应用有所帮助。
关键词: 均匀沙, 起动流速, 复合底坡
Abstract: The researching conditions of incipient velocity of sediment are analysed.Some formula on incipient velocity are reviewed and evaluated. With the aid of experiment data,the differences of velocity on reunite slope and on slight slope are analysed. This is helpful for the use of incipient velocity in practice and research.
Key words: uniform sediment, incipient velocity, reunite slope
