从不同角度对来沙系数的物理意义进行了探讨,认为来沙系数包含以下几层物理意义:①单位流量的含沙量大小;②实测含沙量与临界含沙量的比值;③水沙搭配参数或冲淤判数;④单位水流功率含沙量的大小;⑤非平衡输沙公式中的关键参数。
The physical meaning of sediment-laden factor is discussed from different angles. It is concluded that the sediment-laden factor contains the following physical meanings: (1) the sediment concentration of unit flow; (2) the ratio of measured sediment concentration to critical sediment concentration; (3) Collocated with the parameters or scour and silt judgment; ④ the size of unit flow power sediment; ⑤ key parameters in the non-equilibrium sediment transport formula.
