| Research Abstract |
A simplified model experiment and numerical analyses have been carried out to investigate the effect of the foot reinforcement pile on preventing settlements of ground and tunnel, that occurring in shallow NATM tunnel excavation. Specifically, the influence of the length, installation position and the installation angle of the piles were discussed in this study. Moreover, the effect of pre-ground improvement method, which used together with foot reinforcement pile in the actually field, has also been discussed.
