Analysis and Treatment of Landslide at the Tunnel Portal in Nanjing Road
The landslide at the tunnel portal in Nanjing Road is mainly determined by a weak intercalated layer between the completely weathered bedrock and the strongly weathered bedrock. The weak intercalated layer has low permeability and weak shear strength, and its interface dip outside of the slope. As the consequence, landslide is likely to happen again due to a rainstorm or other inducement. In order to prevent a second landslide, a comprehensive treatment scheme is presented, which implements anti-slide piles as the major treatment and several auxiliary treatments including filling and compacting the cracks, cutting-off and draining water, locally bolt-shotcrete support, and repairing the existing retaining wall and the lattic frame beams. After applying this scheme, the slope stability meets the design requirements.
