摘要
本文较为系统地研究了非均匀沙运动机理及输沙率的计算方法，在建立泥沙运动交换模式的基础上，指出现有非均匀泥沙起动流速公式存在的不足并对此作了修正，然后分别讨论了推移质分组输沙率、悬移质分组挟沙力和全沙输沙率的计算方法，得到的有关公式均用实测资料作了验证计算。结果表明它们是合理、可靠的，可在理论研究和生产实践中参考应用。
In this paper, a model of non-unifom sediment motion and exchange is discussed. Based on the shortcoming of present incipient velocity formulas for non-uniform sediment, the Qin Rongyu's formula is corrected. Then,the methods of calculating bed load transport rate and suspended load transport capacity of each grain size fraction of the non-uniform sediment, and total load transport rate, are studied. The equations obtained in this paper are all verified by measured data. The results show these formulas are rational and reliable.
