| 摘 要： | 新寨隧道位于西秦岭褶皱系中,节理裂隙发育,岩体破碎。进口段位于滑坡左侧边缘,洞门左侧发育冲沟一条,最小埋深13～18 m,在此偏压、浅埋、软弱围岩条件下安全进洞施工难度极大。论文以在建新寨隧道为依托,较详细地记录、分析、总结了施工全过程,得出一些处理类似问题的经验,在指导自身施工的同时,还对类似隧道的施工有着借鉴、指导意义,具有很大的经济效益和社会效益。

| Abstract: | Xinzhai tunnel is embedded in fold system of West Qinling with developed joints and broken rocks.The entrance section of it locates on the left margin of landslip with a minimum overburden of 13～18m,and a gully was developed at the left side of tunnel portal.It is difficult for the safe construction under the condition of uneven pressure,shallow overburden and soft rock.The whole working process has been recorded,analyzed and summarized in detail based on the Xinzhai tunnel practice with experience accumulated to serve guidance for similar projects. |
