| 摘 要： | 以在建成兰铁路松潘隧道为工程实例,探讨研究地下水和构造应力共同作用下炭质板岩隧道变形特征。通过变形原因分析,采取设置长锚杆、注浆加固松散围岩、加强钢拱架锁脚等措施,能够有效控制变形。将软岩变形控制措施纳入动态设计是一种较为经济合理的手段。通过工程试验,动态调整工程措施,优化变形控制方案,对成兰铁路隧道建设具有较好的指导意义和工程借鉴。

| Abstract: | The discussion of carbonaceous slate tunnel deformation control technology under the groundwater condition.It takes under construction Song-pan tunnel engineering of Chengdu-Lanzhou railway as an example in this paper, for studying the deformation characteristics of carbonaceous slate tunnel under the groundwater and the tectonic stress combining action.To set up long bolt and grout loose surrounding rock for reinforcing and strengthen lock foot of the steel arch frame, through analyzing the reason of the deformation, those methods can control the deformation effectively.It is a more economic and reasonable method that taking soft rock deformation control measures into the dynamic design.Dynamic adjustment of engineering measures and optimization the scheme of deformation control which provide a good guiding significance and engineering reference for Chengdu-Lanzhou railway tunnel construction, through the engineering test. |
