| 摘 要： | 根据脉动流速服从正态分布和输沙平衡时床沙与推移质泥沙颗粒的交换处于平衡状态的概念，经理论分析得到了适用于宽级配非均匀沙河槽的推移质输沙率及其级配计算，由非均匀推移质输沙率及其级配计算公式的计算值与Davies、Day、Gessler、Little和Mayer等水槽试验值及美国东汊河、Tanana河、Snake河及长江宜昌等河道实测值吻合较好。

| Abstract: | According to the fact that the fluctuating velocity conforms to the statistics normal distribution, a formula for calculating the wide-range size composition of bed load is established under the law of conservation of sedimentation. The calculated values are in good agreement with the measured data. Results show that the formula is reliable and rational. |

| Keywords: | non-uniform sediments bed load transport rate size composition |
