摘要
节理发育的围岩中隧道施工极易引起塌方,给施工造成极大的安全隐患。文章研究了不同节理倾角下铁路隧道围岩稳定性及支护技术,为山岭隧道节理裂隙发育岩体的隧道施工提供了支持。
It easily causes to collapse when being constructed in surrounding rockamss with joints,and exists potential danger.Study on tunnel construction and support technology for surrounding rockmass controlled by joints was made in this paper,it would provide technical support for tunnel construction.
