摘要
以隧道围岩与支护结构的相互关系为主要研究对象,以特长公路隧道围岩及支护结构稳定性分析方法为依托,对隧道掌子面所揭露围岩岩体、结构特征进行调查、记录,分析掌子面围岩等级,并与设计资料进行对比,对不同级别不同地质条件下的围岩与支护结构稳定性进行比较分析,总结围岩及支护结构稳定性分析的方法。
Focusing on the relationship of surrounding rocks and supporting structures of tunnels and based on the analyzing methods of the surrounding rocks and the stability of supporting structures of long highway tunnels,the exposed surrounding rock mass and structure characteristics of tunnel workface are studied and recorded,the levels of surrounding rocks are analyzed,and compared with the design information,the surrounding rocks and supporting structures of different levels in different geological conditions are analyzed to summarize the analyzing methods.
