本文简述了细颗粒土在水中沉降规律,用比重计法分析土颗粒的试验原理,甲种和乙种比重计的设计制造方法。根据国内外资料提出了使用比重计法分析土颗粒的精度要求。建议由使用部门和玻璃仪器工厂密切配合,迅速统一生产出合格的土颗粒分析比重计,从而改变我国各使用单位进行土颗粒分析比重计刻度校正工作的状况,以提高试验质量和工作效率。
This paper briefly describes the sedimentation law of fine-grained soil in water, the analysis principle of soil particles by pycnometry, and the design and manufacturing methods of a- and B-type hydrometers. Based on domestic and foreign data, the accuracy requirements for the analysis of soil particles using the hydrometer method were proposed. It is suggested that the use department and the glass instrument factory should closely cooperate with each other to quickly and uniformly produce a qualified soil particle analysis hydrometer, thereby changing the status of calibration of the soil particle analysis pycnometers in various units in China to improve the test quality and work efficiency.
