摘要
在对比国内外大变形隧道产生变形的原因及处理措施的基础上,通过施工现场实践,针对关角隧道板岩破碎地段的开挖支护经验进行了总结,并整理出了单线铁路隧道在板岩破碎地段的合理支护参数和断面形式,为今后相近工程的设计及施工提供了指导。
Based on the comparison of reasons for the deformation of tunnels with large deformation and treatments at home and abroad,the study sums up the excavation support experience of the slate crushing section along Guanjiao Tunnel by the practice at the construction site,and indicates the reasonable support parameter and section forms of the single-route railway tunnel at the slate crushing section,so it provides the direction for the design and construction of similar projects in future.
