AbstractA set of new equations are presented for predicting the saltation parameter, the sediment transport rate of bed load and the suspended load for each specific grain size group in a mixture. Fifty seven sets of test data on the transport capacity of graded sediment are published. The mutual effect of fine and coarse grains on transport rate is analyzed and the effect coefficient K D of non uniformity of a mixture is introduced and its expression is proposed. The calculated results from the author′s equations are in good agreement with the observed data.
本文從床沙、推移質及懸移質互相交換、銜接的物理圖形出發,在力學、隨機及紊動擴散分析基礎上,提出了顆粒躍移及推移質、懸移質和全沙統一的新的非均勻沙挾沙力公式.文中公布了新近試驗取得的57組非均勻沙挾沙力水槽資料,分析提出了反映混合沙中粗細顆粒互相影響的系數的關系,提出了懸移層與推移層交界面高度及濃度預報新的初步關系.應用本文提出的挾沙力系列公式計算驗證了大量天然河流及水槽實測分組和總挾沙力資料,計算與實際符合較好.
