More Information
Summary:The invention discloses a tunnel structure capable of reducing slope excavation and a construction method thereof. The structure comprises a tunnel body intersected with a slope; a concrete retainer wall is vertically arranged on the side wall, near the slope, of the tunnel body; and a reinforced concrete sleeve arch matched with a vault of the tunnel body is arranged at the top of the concrete retainer wall. The construction method comprises such steps as field investigation, construction preparation, half-bright tunnel construction, half-dark tunnel and support. The structure adopts the half-bright and half-dark tunnel to solve the environmental damage problem caused by large-scale slope excavation, changes passive to active compared with a traditional method, shortens the construction period, and improves the project benefit. 本发明公开了种能减少边坡开挖的隧洞结构及其施工方法，该结构包括与边坡相交的隧洞本体，隧洞本体靠近边坡的侧壁设有竖直布置的混凝土挡墙，混凝土挡墙顶部设有与隧洞本体拱顶相匹配的钢筋混凝土套拱；施工方法包括现场勘察、施工准备、半明隧洞施工、半暗隧洞及支护等步骤。本发明采用半暗半明隧洞解决了大规模开挖边坡带来的环境破坏问题，且与传统方法相比变被动为主动，缩短了施工工期，提
