摘要
膨胀岩隧道洞口段施工中变形问题较为多见,整治有一定难度。阐述玉蒙铁路新寨隧道进口段施工过程中隧道洞口的变形情况、变形处理方案、支护措施及效果监测。研究能够为浅埋膨胀岩隧道洞口段的变形处理提供案例借鉴。
The problem of deflection of tunnel portal in shallow buried swelling rock is very common and there is some difficulty in dealing with it. This paper describes deflection situation, processing program of the deflection, supporting measures and effect monitoring in the construction process of the tunnel portal entrance of Xinzhai tunnel on Yuxi -Mengzi railway. This research provides a case study and make reference to deflection processing methods of tunnel portal in shallow buried swelling rock.
