摘要
本文在前人的理论分析及水槽试验工作的基础上，分析了上举力系数对边坡泥沙起动影响，研究了常用模型沙（木屑、煤屑、电木粉），以平床泥沙起动相似设计。
Based on the obtained results of theoretical analyses and flume tests, the impact of the coefficient of verticaility force from fluid flow around particles on the incipient motion on side slope is studied in this paper. The authors discuss the characteristics of deviation of commonly used model sand (wooden filing sand, coal slack sand and phenolic moulding powder sand) caused by scale distortion on the similarity of incipient motion on gradient river bed (side slope bed and river longitudinal profile slope bed) when designed as flat river bed.
