摘要
以五指山隧道工程为例,对洞口开挖施工及明洞施工的要点进行了归纳总结,通过隧道实践施工证明,对于斜交、偏压、浅埋隧道,在进行洞口边坡以及仰坡开挖时,使用长管棚和长护拱形成半明洞是十分有效的施工方法。
Taking Wuzhishan tunnel engineering as an example,the paper summarizes the entrance excavation construction and open entrance construction points.Tunnel practice construction proves that： long-pipe and long arch support and half-open tunnel are effective construction methods in entrance slope and upper slope excavation for inclined,bias and shallow-embedded tunnel.
