河流泥沙颗粒分析方法泥沙颗粒级配是河流泥沙的重要特性之一,也是泥沙研究的一个必要项目。天然河流泥沙粒径分布范围很广,必需用几种方法互相结合以求得其级配。在常用的分析方法中,直接量度法和筛分析法仅适用于砂及砾石类较粗泥沙的级配分析,而小于1.0毫米的细砂、粉土、粘土等较细泥沙的分析则多用沉降方法进行。多年来国内外一直沿用的 River sediment particle analysis method Sediment particle size distribution is one of the important characteristics of river sediment and is also a necessary project for sediment research. Natural river sediment size distribution is very wide, must be combined with each other in several ways to obtain its gradation. Of the commonly used analytical methods, the direct measurement method and the sieve analysis method are only applicable to the grading analysis of coarser sediments of sand and gravel, while the analysis of fine sediments of fine sand, silt and clay smaller than 1.0 mm Multi-settlement method. Over the years has been used at home and abroad
