浅埋段自进式锚杆施工在山区隧道工程的应用

Application of Self-propelled Bolt Construction in Shallow Section in Mountain Tunnel Engineering

以摩天岭隧道为研究背景,分别从施工方法、施工工艺等方面,对浅埋段自进式锚杆施工技术应用要点进行详细解析。通过浅埋段自进式锚杆施工技术在隧道工程中的合理运用,得出施工中围岩未出现滑塌、自进式锚杆形成了很好的棚护、初期支护稳定的结论。

Taking the Motianling Tunnel as the research object, this paper makes a detailed analysis of the application points of self-propelled bolt construction technology in shallow section from the aspects of construction method and construction technology. Through the reasonable application of self-propelled bolt construction technology in tunnel engineering in shallow section, it is concluded that the surrounding rock did not collapse during construction, and self-propelled bolt formed a good shed support, and the initial support was stable.
