【摘要】 本文基于Ｐａｒｋｅｒ等人泥沙输移矢量式的分析和研究，增加了上举力的作用，并考虑了泥沙颗粒受力非平衡条件，采用牛顿力学的矢量分析法，推导了泥沙输移的通用矢量式．经对公式简化，且用Ｉｋｅｄａ和笔者试验资料的验证，证明计算值与试验值吻合较好．更多还原

【Abstract】 Based on the analysis and research of Parker vectorial bedload formula, a kind of general vectorial bedload transport formula is deduced by adding lift force and taking non equilibrium forces acting on sediment particle into account. The calculated result of the simplified formula is compared with the experimental data as well as from Ikeda and the authors. It is shown that the calculated results agree well with the observed data.更多还原
