In this paper, it is planned to use numerical modeling to investigate the ground movement due to tunneling construction in soft ground. The proposed method is used for analyzing the under construction tunnel of Cairo Metro–Line III. Most of the length of this line will be constructed by Tunnel Boring Machine (TBM). Two and three-dimensional numerical analyses are applied to simulate this tunnel and approach for prediction of the settlement due to tunneling in soft ground by using Plaxis program. The resulted settlements of these analyses will be compared with the measured values which be gained from the field data in the site. Reasons for any differences are explained. The results of these models are promising; help to minimize the construction cost and help the decision maker to choose the optimum solution for the other phases and other lines in the future |
