| 摘 要： | 几乎所有的士工试验规范均要求细碎屑土在颗粒分析前进行浸泡处理。现从机理上探讨这种预处理对於软土试样的必要性。经对比试验证实,除软粘土外其余各类软土均无必要。文章还探讨了用天然土样直接测试的可能性。

| Abstract: | Almost every soil test code demands soaking treatment for fine clastic soil before grain -size analysis. The necessity of this treatment is discussed through inquiring into mechanism. There is no need to soak all kinds of soft soil except clay before grain -size analysis by contrasting test. The possibility of direct test with natural soil is also discussed. |
