| Abstract:Ajialing tunnel was planed passing the existing railway. By the comprehensive control technology of pre-support with cavern pipe shed, settlement feedback excavation method, primary support strengthening, monitoring measurement technology and monitoring on cavern pipe shed deformation, the settlement of the existing railway is effectively controlled. According to the tunnel construction conditions, this comprehensive technology breaks through the conventional construction methods and process, and provides the reference for the similar tunnel construction. |
