中文摘要：

为研究庙岭隧道围岩变形规律,并对其洞室稳定性进行评估;通过现场勘察,收集及整理该工程的地质资料、施工工艺、围岩变形监测数据,对隧道围岩变形规律分别从时间和空间两个角度进行回归分析,结果表明,隧道所采用的台阶法施工、设计的初期支护参数是合理的,满足施工安全和洞室稳定性要求,进一步得到隧道围岩变形随时间和空间变化的关系,找到了控制洞室稳定性的关键点,为其他类似工程控制洞室稳定性积累了经验。

英文摘要：

The distortion of Miaoling tunnel wall rock was studied,and the cavity stability of the tunnel was assessed in this paper.Through on-site survey,collecting and sorting the geological data,construction technology data and rock deformation monitoring data,deformation of the wall rock was analyzed from the perspectives of time and space.The results show that the initial support parameters determined by the step construction method and used in design and construction of the tunnel is reasonable and fulfills the requirement of construction safety and cavity stability.The tunnel rock deformation along with time and space was obtained and the key that controls cavity stability was found,which provides a ground for cavity stability control of other similar projects.
