采用动态图像法和激光法对黄河干流悬移质泥沙样品进行泥沙粒度分析,构建了动态图像法与激光法粒度成果之间的相关性。利用激光粒度分析技术得出粒度分布的中值粒径D50,再利用粒度粒形分析技术分析,结果显示动态图像法粒度成果与激光法粒度成果在不同级配之间的关系基本一致,动态图像法获得的粒度分布的D50通常大于激光法获得的D50。
Sediment particle size was analyzed by dynamic image method and laser method on sediment samples of suspended sediment in the Yellow River, and the correlation between dynamic image method and laser particle size was established. The particle size distribution median diameter D50 was obtained by laser particle size analysis, and then analyzed by particle size analysis. The results showed that the relationship between the particle size of the dynamic image method and the graded laser particle size results were basically the same. The dynamic images The D50 of the particle size distribution obtained by the method is generally larger than the D50 obtained by the laser method.
