Abstract
The authors performed numerical analyses by rigid-plastic finite element method to clear a reinforcing mechanism and settlement reduction effect of side piles. As a result, the authors found that the reinforcing mechanism of the side piles is to keep the slip line away from the tunnel and prevent a concentration of a failure area. The authors also found that the side piles need to have the enough length to cross the slip line and the side piles become effective when the side piles are fixed to the tunnel tightly, the ground has large internal friction angle, and the side piles is installed at lower part of the tunnel.
