| 摘 要： | 结合某段煤矸石路基的填筑,研究煤矸石路基压实度、路基沉降与压实遍数的对应关系.结果表明:对煤矸石路基进行冲击压实后,路基强度和刚度大幅度提高,压实度达到了95％以上；沉降量在15遍以前较大,15遍以后趋于稳定:对煤矸石填充路基顶面的弯沉测试数据进行计算,结果也满足施工要求.

| Abstract: | Combined with the filling of coal gangue subgrade of a certain section, the relation between the compaction degree and settlement of subgrade and compaction times was studied. The results indicate that both the strength and stiffness of subgrade are improved after the impact compaction, and the compaction degree reaches 95% and above; the settlement is major at first, but it becomes stable after 15 times of compaction; the result of calculation on deflection data of the surface of coal gangue subgrade also meets the requirements of construction. |
