摘要
利用比重计法与传统的吸液管法分析试样在粒度级配曲线、定名、粘粒含量、不均匀系数、中值粒径等方面的差异 ,发现两种方法的结果基本上是一致的。但比重计法易受容器的大小形状的影响 ,如容器的有效深度过小 。
Soil's granularity content is an important parameter in the studying of geology and engineering geology. This paper uses hydrometer analyse and pipette method respectively to analyse the differences in the grain gradation curve, definition, clay content, coefficient of uniformity, average grain diameter .and so on. From the result of analysis I find all the aspects above are basic uniform. However hydrometer analysis method is often affected by the size and shape of container .If the effective depth of container is too small, the clay content of soil sample in this method will be too high.
