摘要
我国中西部铁路扩建复线工程中,由于地质条件限制,不得不穿越滑坡区段,施工新建隧道时易引起隧道变形与滑坡体变形。采用注浆技术加固隧道围岩后,从注浆理论出发,建立注浆围岩的力学模型并进行数学分析,同时给出了隧道注浆控制方法和检测结果。
The double railway lines are being constructed in centro-west China. Because of the geography condition, many tunnels have to go through landslide areas. If the new tunnel is put in the landslide area, collapse and cave-in will take place during tunneling. More serious outcomes are that the interval between the existing tunnel and new one is very small, so that it is very easy to cause the existing tunnel in soft rocks to deform and fail. This case occurs several times in the centro-west railroad of China. Case study of grouting for the surrounding rocks of tunnel in the landslide area is made, including design, implementation and back-check of grouting effect. The reason of deformation of existing tunnel is analyzed with numerical method, and the grouting method under the special condition is discussed.
