| 摘 要： | 本文阐述了宽级配河床粗化稳定结构的特性,得到了宽级配河床粗化稳定后的阻力规律、非均质沙起动概率及粗化层级配的计算方法,并利用各家水槽资料、San Luis河流(美国)及汉江丹江口水库下游资料与阻力公式及粗化层级配计算值进行了比较,二者基本吻合。

Armoring Stable Structure of Riverbeds with Wide Size Distribution |
| |
| Abstract: | The characteristics of armoring stable structure of riverbed with wide size distribution have been presented in this paper. The resistance of riverbed , the threshold probablity of sediment motion and the calculation method of size distribution of armor layer have been obtained The calculated results of the resistance formula and size distribution of armor layer are in a good agreement with experimented al ues of five kinds of data and measured values of san Luis valley canal and Hangjian river |
