摘要
结合隧道工程实例,总结小净距立体交叉隧道环形导坑开挖、弱爆破、围岩加强等工艺特点、适用范围、工艺原理、施工工艺流程及操作要点,可为类似工程的施工提供参考。
By combining tunnel engineering examples,the paper summarizes the technological characteristics, the scope of application,the technical principle, the construction technology process and the operation instructions for ringlike drift heading excavation, weak blasting and surrounding rock reinforcement of super-closely-spaced intersecting tunnels,which can be used as reference for similar projects.
