| 摘 要： | 砂砾是一种广泛用于路基修筑的建筑材料,但由于其棱角比较圆滑,造成较难压实的问题。利用砂砾和石渣在抗剪强度性质上的差异,提出了改善砂砾内摩阻力的方法,并在试验室进行了振动压实成型试验,为现场改善砂砾路基的压实效果奠定了基础。 |

| Abstract: | The Sand-gravel is a construction material which is extensively used for subgrade building.But it is difficult to compaction owing to its silck edges.Based on difference of gravel from rock ballast in shear resistance,the paper presents the method for improving internal friction of gravel and makes test for jolt moulding in lab,that play foundation for improving the compactive efficiency of sand-gravel subgrade in situ. |
| Keywords: | Subgrade engineering Sand-gravel filler Vibrating compaction |
