Abstract

In this thesis ABAQUS finite element software is used to numerical simulate and analyze the excavation process of root piles in reinforcement tunnel basis,finding that the invert rebound amount decreased obviously after the root piles used in tunnel reinforcement,aslo the firet main stress and the third main stress are reduced.The result shows that the root piles could be used to reinforce the foundation to improve the soil capacity,reduce the tunnel lining force and maintain the stability of surrounding rock in softweak loess region.
