| 富水浅覆不均匀地层大断面隧道快速施工技术研究(52卷) |
| 英文标题 |
| Study on rapid construction technology of large-profile tunnel in water-rich , shallow buried and complex stratum |
| 摘要 |
| 针对江门隧道下穿玉龙湖泄洪道段存在的富地表水、超浅埋、上软下硬地层、大断面等特点，施工期间极易引起塌方，风险极大。为此对地表泄洪道进行必要处理，同时采用水平旋喷和管棚注浆加固围岩，结合台阶法开挖，现场施工时加强施工控制与管理，确保了隧道在该地段的施工安全与质量，同时加快了施工进度，可供类似工程参考。 |
