| 摘 要： | 在回顾前人成果的基础上,依据天然河流资料和以轻质模型沙资料,对适用性较强的各家泥沙起动流速公式进行了验证。结果表明:①以某一较小的单宽输沙率作为判别标准即使有一定依据,但在推移质输沙率测验精度很低的前提下,利用具体天然河流资料确定的泥沙起动流速误差也较大;②现有各家泥沙起动流速公式计算结果较为相近,同轻质模型沙起动流速都相差不大,对于天然河流资料也可进行估算;③相对而言,张红武、卜海磊公式,沙玉清公式,唐存本公式,计算结果同实测资料较为接近,可用来计算天然河流起动流速,其中张红武、卜海磊公式的验证结果最佳。 |

| Abstract: | Based on the review of achievements,seven sediment incipient velocity formulas of high applicability were verified by the natural rivers’ data and light model sediment experiment data.The results show that a) there is a bigger error between the calculation and the measured value under the conditions of the natural data,when the bedload sediment transport rate measure accuracy is very low;b) the calculation results of the seven formulas is more similar,especially under the conditions of the light model sediment experiment;c) relatively,the calculation results of the ZHANG Hong-wu and BU Hai-lei formula,SHA Yu-qing formula and TANG Cun-ben formula approaches the natural data,and the accuracy of the ZHANG Hong-wu and BU Hai-lei formula is better than others. |
