对黄河实测资料分析及高含沙水流输移机理研究表明，窄深河槽具有极强的输沙能力，艾山以下河道在流量３０００～４０００ｍ￣３／ｓ时，实际上已经输送过合沙量２００ｋｇ／ｍ￣３的洪水，若含沙量增加到４００～５００ｋｇ／ｍ￣３时，更容易输送，甚至对ｄ＿（５０）＝０．１ｍｍ的粗沙也能顺利输送。以控制流态在充分紊流区，适宜输送的含沙量上限可达８００ｋｇ／ｍ￣３。 The analysis of the measured data of the Yellow River and the transport mechanism of high sediment flow show that the narrow and deep fluvial channels have extremely strong sediment transport capacity. When the flow below Isishan reaches 3000 ~ 4000m ~ 3 / s, it actually has transported sediments 200kg / m ~ 3 flood, if the sediment concentration increased to 400 ~ 500kg / m ~ 3, more easily transported, and even d_ (50) = 0.1mm of coarse sand can be smoothly transported. In order to control the flow in a fully turbulent area, the upper limit of sediment suitable for transportation can reach 800kg / m ~ 3.
