临界水深计算方法的研究

Research on calculation method for critical water depth

总结了渠道临界水深常见的计算方法,分析了过水断面比能曲线的特性,根据渠道临界水深的定义,利用计算机软件编程技术可以解决大量繁琐计算的特点,求解了明渠临界水深,并且分析与总结了用定义法解决工程计算的意义。

Firstly,common calculation methods for the channel critical depth has been summarized,and the characteristics of specific energy curve of flow cross-section have been analyzed in this paper.By using computer software programming technology that can solve the massive trival calculation,based on the definition of the channel critical depth,the critical water depth was solved.And the significance of using the definition method to solve engineering calculation has been analysed and summarized.
