Particle-scale Analysis of Key Technologies on Cut-and-over Tunnel in Slope Engineering

When the shallow tunnel is constructed on the slope terrain in the mountains, there are the potential risks such as landslide induced by cutting the slope and the non-compacted backfill material during the construction of the cut-andcover tunnel. In order to solve these problems, based on a practi...

In order to solve these problems, based on a practical engineering, the optimized construction plans of the cut-and-cover tunnel were analyzed by particle flow code (PFC), the key parts of the open-cut construction were identified, and the anti-slide piles countermeasures were proposed.
