摘　　要：根据静水沉降颗粒分析法计算公式原理,分别采用了常用的密度计法和移液管法求取细颗粒土的粒径级配,分析了两种方法试验误差产生的原因,并证明密度计法较移液管法具有更简便、准确、节能的特点,建议尽量采用密度计法。According to Principle of quiescent sedimentation granula analysis, the densimeter method and the piette method are used to get the size grading of fine-grain soil and the errors of two methods are analyzed. The test result shows that the densimeter method, compared to the piette method, is convenient, accurate and energy-conserving. Therefore, it is suggested that the former is used as far as possible.

关 键 词：密度计法 移液管法 颗粒分析
