| Abstract | Tunneling adjacent or beneath to an existing piled foundation may induce additional pile settlement, lateral movement which may leads to induce extra axial force and bending moment in the piles. It may also induce differential settlement among the piles which cause redistribution of load among the piles. In this study 3D numerical analysis has been performed in order to perceive the effects of tunneling induced ground movements on pile foundation. To predict tunnel pile interaction four case studies including one centrifuge model has been selected from Bangkok, Hong Kong and Singapore sub soils. All the case studies are analyzed in two stages, 1st in greenfield condition to validate the model for given volume loss and in 2nd stage tunnel pile interaction analysis is performed. In all the case studies greenfield analysis results and pile response are compared with the measured data and previous studies results. Also the peak factored values of axial forces and bending moments are plotted within the moment interaction diagram of pile and it is found that in all the cases they fall within the ultimate pile structural capacity envelop. Finally, a comparative study has been conducted to understand tunnel pile interaction in Bangkok, Hong Kong and Singapore sub soils. Highest volume loss and surface settlement is predicted in Singapore sub soil while lowest in Bangkok sub soil. The effects of tunneling induced soil movements are higher on a single pile than piles in a group and within a group nearest piles influenced more than farther piles. |
