摘要 基于任意面上非粘性沙颗粒的受力分析,考虑了非平衡条件,推导了更具普遍性的泥沙输移矢量式。文中经对公式简化和编程计算,并对计算值与Ikeda和笔者顺直河道河宽调整试验资料加以验证。两者吻合较好。 Based on the analysis of non equilibrium forces acting on a non cohesive particle, the general vectorial equation of bedload transport is derived. Computation was carried out after certain simplifications with regard to a number of formulas, the results obtained being in good agreement with experiments.
