介绍了处理浅埋隧道塌方的施工工艺,结合塌方长度及周围岩体情况等,选择施工方法。抢风岭隧道在无任何征兆下突然塌方,土体呈粉状,综合分析塌方原因后,采用小导管注浆法处理塌方,待临时拱架及径向小导管注浆结束后,加强对周边位移的监控,随时掌握塌方体的变形情况。
The construction technology for dealing with landslides in shallow tunnels is introduced. Based on the length of landslide and the surrounding rock masses, construction methods are selected. Zhaofengling tunnel without any signs of sudden collapse, soil powder, a comprehensive analysis of the cause of landslides, the use of small conduit grouting method to deal with landslides, temporary arch and radial small duct to be grouting after the end of the strengthening of the surrounding Displacement monitoring, grasp the deformation of landslides at any time.
