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...

description |
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 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. Furthermore, the grouting reinforcement process for
the non-compacted backfill material around the shallow tunnel was simulated by PFC, and the variation characteristics of
the porosity and grouting pressure were revealed as well. The results are of great value to the similar engineering. |
