| 摘 要： | 由于水流挟沙力公式众多,对水流挟沙力公式的检验显得尤为重要。本文对水流挟沙力公式的检验方法进行了评述,并利用实测资料及有关计算公式,对常用的几种检验方法进行了比较分析。结果表明,对于相同检验资料,不同检验方法得到的结果并不相同。产生差异的主要原因有两点：其一,不同检验方法考虑的侧重点不同 其二,差别较大的检验资料对检验结果的影响权重不同。目前,建议同时运用相关系数法和集中系数法综合检验水流挟沙力公式。 |
| 关 键 词： | 水流挟沙力 最小距离 相关系数 |

| Abstract: | It is very important to choose a reasonable sediment-carrying capacity formula from a large amount of formulae to calculate sediment concentration in natural rivers.Some verification methods are used to evaluate the ability of selected formulae.The results show that different verification methods can get different conclusions.There are two main reasons lead to such difference.Firstly,different verification methods attach importance to different points.Secondly,different verification data lead to the differe... |
| Keywords: | sediment carrying capacity minimum distance correlation coefficient |
