摘要
现有的水槽试验资料及天然河流实测资料表明，在水流输沙计算中考虑泥沙级配对水流挟沙力的影响，能够深入地把握水流挟沙的力学机制，进而提高输沙计算的精度。
The flume experiment data and meadowed data of river show that if in sedi ment disilharge calculation, the influence of sediment grading on the sdeiment-carrying capaci ty is taken into account , it can help better grasp the mechanism of sediment carring capacity and upgrade the accuracy of calculation.
