摘要
指出安全进洞是整条隧道顺利施工的前提,结合工程概况,介绍了龙池隧道出口洞口浅埋段采用明拱暗墙法进洞的具体施工方法,得出了明拱暗墙法既可确保洞口边仰坡稳定,又可节省明拱顶部的大管棚,是一种科学有效的施工方法的结论。
The author points out that entering portal safely is the premise of the smooth construction of the whole tunnel, the author introduces the concrete construction method of the portal excavation of the shallow buried section of Longchi tunnel by open arch and subsurface wall, draws a conclusion that the method of the open arch and subsurface wall can guarantee the stabilization of the slope around tunnel entrance, also can save the pipe shed in the top of the open arch, and can be the scientific and efficient construction methods.
