对于粘性土<0.1mm以下颗粒组成的测定,当前用得最多的是比重计法和吸管法。但这两种方法,都是要预先测定土粒比重和试样干重的,既费时间,又费人力,本文介绍的悬浮土粒法正是为探讨不预先测定土粒比重和试件干重而提出来的一种分析方法。一、悬浮土粒法的基本原理悬浮土粒法和吸管法系同一原理,为测定土中某粒径d的成分,必先按斯笃克
For the determination of particle composition below <0.1mm in cohesive soils, the pycnometer method and pipette method are currently used most frequently. However, both of these methods are required to determine the proportion of soil particles and the dry weight of the sample in advance. This is time-consuming and labor-intensive. The suspended soil method described in this paper is to explore the issue of not determining the proportion of soil particles and the dryness of the sample. A method of analysis proposed again. First, the basic principle of suspended soil method Suspended soil particle method and sucker law the same principle, in order to determine the composition of a certain particle size of soil d, must first according to Sri Lanka
