摘要
通过韩家岭隧道现场工程地质工作,阐述了隧道多层开挖方法以及大管棚、小导管、锚杆等超前支护措施;最后,针对现场施工提出了几点有意义的建议。
By geology study of Hanjialing tunnel,the multi-layer excavating method of tunnel and the pre- support methods,such as big diameter tube supporting system,small diameter tube supporting system and bolt are presented.Some meaningful suggestions are proposed for the construction of tunnel.
