摘要
根据公路隧道施工经验,从硬质岩浅埋大断面公路隧道施工方法的确定谈起,对掌子面超前预注浆和锚杆加强、纵向连接加固、弱爆破等施工技术进行了详细分析。通过对硬质岩进行大断面施工技术的处理,使公路隧道开挖难度得到降低,以保证整体的公路隧道施工进度,从而提高公路隧道整体结构的稳定性及安全性。
According to the construction experience of highway tunnel itself, to determine the first hard rock shallow buried highway tunnel con-struction method about, for face pre grouting and anchor reinforcement, longitudinal connecting reinforcement, weak blasting construction tech-nology are analyzed in detail. Through the treatment of hard rock＇s large section construction technology, the difficulty of highway tunnel excavation is reduced, so as to ensure the overall construction progress of the highway tunnel, thereby improving the stability and safety of the overall structure of the highway tunnel.
