| 中文摘要: |
| 通过砂土做道路路基，对其进行了击实、抗剪、压缩模量、CBR值等比较系统的研究，指出了砂土作为路基的填料其剪切强度随着含水量的增加有一个最佳值，压缩模量随着法向应力的增大而增大，CBR值随着压实度的增加，明显增大，但是浸水状态时要降低得多。 |
| 英文摘要: |
| In this paper, a systematic study is carried out on the road embankment of sand through tests of compaction, shear resistance, compression modulus and CBR value. It is pointed out that there is an optimum value of the shear strength of sand as the subgrade fill as water content changes; The compression modulus increases with the increase of normal stress; CBR value increases obviously as the degree of compaction increase, but reduces remarkably in flooding state。 |
