摘要/Abstract

摘要： 水流挟沙力是运用河流动力学原理进行河床冲淤计算的重要指标，对常见的水流挟沙力公式进行了检验，检验所采取的判别方法有：相关系数法、最小距离法、集中系数法、偏离系数法和聚类分析方法。结果表明：相关系数法、最小距离法、集中系数法、偏离系数法的检验结果在整体趋势上是一致的，但检验结果相互间存在一定的偏差；而聚类分析是根据聚类标准将不同的公式划分为不同类别，视同一类的计算效果相当，能将其他几种方法的结果较好地统一起来。

Abstract: Sediment carrying capacity is an important parameter in the analysis of river process. This paper verifies a great deal of sediment carrying capacity formulae and adopts some verification methods. The verification methods include correlation coefficient method, least distance method, convergence coefficient method, error coefficient method and clustering analysis method. The results obtained from the correlation coefficient method, least distance method, convergence coefficient method and error coefficient method disagree with each other in some differences, but cluster analysis method can unify the other four methods result.
