| 富水淺覆不均勻地層大斷面隧道快速施工技術(shù)研究(52卷) |
| 英文標(biāo)題 |
| Study on rapid construction technology of large-profile tunnel in water-rich , shallow buried and complex stratum |
| 摘要 |
| 針對江門隧道下穿玉龍湖泄洪道段存在的富地表水、超淺埋、上軟下硬地層、大斷面等特點(diǎn)，施工期間極易引起塌方，風(fēng)險(xiǎn)極大。為此對地表泄洪道進(jìn)行必要處理，同時(shí)采用水平旋噴和管棚注漿加固圍巖，結(jié)合臺階法開挖，現(xiàn)場施工時(shí)加強(qiáng)施工控制與管理，確保了隧道在該地段的施工安全與質(zhì)量，同時(shí)加快了施工進(jìn)度，可供類似工程參考。 |
