摘要
到目前为止,研究悬移质不平衡输沙,基本上都是按均匀泥沙进行因而只研究含沙量沿程变化。对于实际的非均匀悬移质,在不平衡输沙时,不仅含沙量沿程变化。同时悬移质级配将会发生变化,相应地床沙级配也会发生变化。显然不平衡输沙的全面研究,应包含上述三方面的内容。
This paper presents the basic rules of non-equilibrium transportation of non-uniform suspended load,including fundamental equations,variations in sediment concentrations along water courses,sorting of gradations of suspended materials during the scouring and depositing processes,the coarseness or fineness of bed materials,etc.The corresponding formulae,checked with considerable measurement data are given.Furthermore,the conditions of equilibrium transportation and composition of the carrying capacities of flowing water are discussed.
