| 摘 要： | 使用HM-1型回弹模量仪对路基非饱和含粘砂土进行了6个不同含水率、5个不同干密度的回弹模量试验。试验表明：含水率和干密度对非饱和含粘砂土的回弹模量影响显著：在同一干密度和含水率下,砂土的回弹模量为一常数;在同一干密度下,随含水率的增大,回弹模量明显减小;在同一含水率下,随干密度的提高,回弹模量明显增大。

| Abstract: | 6 different water contents and 5 different dry density resilient modulus tests are carried out by using HM-1type resilient modulus instrument to unsaturated subgrade clayed sand.The tests reveal that water content and dry density have great effect on resilient modulus of clayed sand.Clayed sand is a constant under the same water content and dry density.With the increase of water contents,the resilient modulus will decrease under the same dry density.With the increase of dry density,the resilient modulus will increase under same water content. |

| Keywords: | unsaturated clayey sand water content resilient modulus |
