| 摘 要： | 针对大跨浅埋隧道极软岩富水界面段施工,传统处理方法多为帷幕注浆固结,但此种工法存在施工周期长、工程造价高等缺点。兰渝铁路咀头隧道在此地质施工时,针对隧道埋深浅的特点,采用地表高压旋喷加固,结合洞内分部开挖、φ89钢管锁脚配合强支护参数等综合措施,达到了快速、安全、经济施工,对类似工程的施工有一定的借鉴和参考价值。 |

| Abstract: | Traditional curtain grouting consolidation is usually adopted for shallow large-profile tunnels in very soft rock interface with rich water,which has the shortcomings of long construction period and high construction cost.While pressurized rotary jet grouting consolidation from ground surface,excavation by parts and steel tube arch abutment as well as proper support parameters were adopted in Zuitou tunnel on Lanzhou-Chongqing railway,considering the geological condition and mined shallow excavation of the ... |
