| 標(biāo)題 |
| 采用液壓夯實機補強高速公路臺背路基施工參數(shù)的試驗研究(49 卷) |
| 英文標(biāo)題 |
| Experimental study on construction parameters used in reinforcing of expressway subgrade at rear of bridge abutment by hydraulic ramming machine |
| 摘要 |
| 測試分析高速液壓夯實機的夯實勢能、夯擊厚度及夯實次數(shù)對臺背路基不同深度的動應(yīng)力和變形的影響，對比分析夯實前后路基不同深度的基本承載力和壓實度變化特性，同時對臺背混凝土動應(yīng)變進(jìn)行了測試，并提出了夯實機施工工藝建議，建議路基夯實高度≤2 |
