Deformation and Failure Mode Analysis of the Tunnel Structure Based on the Tunnel-Related Landslides Cases

When the tunnel passes through slope area, once stability changes or landslide disasters occur, large additional stress, deformation, cracking are easily caused in tunnel, which results high risk to operation. The deformation and failure mode of induced by different types tunnel-related landslides different. However, there is no systematic classification structure systems. By investigating typical cases diseases China, this study analyzes relationship between disease characteristics. It also summarizes five modes corresponding characteristics determines modes. This can provide a technical support for identification practical engineering applications. Finally, it provides reference location selection, design structure, treatment areas.
