| 采用液压夯实机补强高速公路台背路基施工参数的试验研究(49 卷) |
| 英文标题 |
| Experimental study on construction parameters used in reinforcing of expressway subgrade at rear of bridge abutment by hydraulic ramming machine |
| 摘要 |
| 测试分析高速液压夯实机的夯实势能、夯击厚度及夯实次数对台背路基不同深度的动应力和变形的影响，对比分析夯实前后路基不同深度的基本承载力和压实度变化特性，同时对台背混凝土动应变进行了测试，并提出了夯实机施工工艺建议，建议路基夯实高度≤2 |
