| 摘 要： | 采用试验的方法对施工路段路基是否适合采用冲击碾压法施工进行了验证。试验发现该路段冲击碾压10遍以后沉降量变化不明显，15遍即可满足规范要求；弯沉值无明显变化规律；原有路基压实度变化在1％以内，各项指标均符合规范要求。研究结果表明同类路段可采用冲击碾压法进行施工．

| Abstract: | The impact compaction tests are carried out to verify if the impact compaction method is adequate for the construction of subgrade.It is found out that the settlement doesn't change much when the compaction times reach 10,and specification requirements will be satisfied with 15 times of compaction;the deflection doesn't change following an obvious rule;the change of compaction degree of origin subgrade is within 1%.The research indicates that impact compaction method could be applied on similar roads. |

| Keywords: | impact compaction settlement compaction degree deflection value |
