1) bed roughness
床面糙率
1.
The relationship between riverbed roughness and its fractal dimension is obtained according to the experimental data and compared with the relationship between roughness and representative diameter.
本文在分析非均匀沙床面颗粒随机分布特性的基础上，对床面颗粒暴露度函数关系进行了分析，通过简化颗粒的排列方式，利用分形理论研究了初始及粗化床面糙度的分形特征，结合实验资料讨论了床面糙率ｎ与糙度分维数Ｄ的关系，并与床面糙率ｎ和代表粒径（ｄ５０、ｄ９０）的关系进行了比较，初步认为对于初始床面分维数与床面糙率具有更好的相关关系，而粗化床面两者代表性基本一致，为更好地研究床面糙率、泥沙起动及其输沙过程提出了一种新的研究方法。
