Title: The Effect of Tunnelling on the Adjacent Single Pile
Abstract: A series of three-dimensional (3D) numerical analyses have been conducted to study the effects of tunnelling on the adjacent single pile. In the numerical analyses the interaction between the tunnel and the pile constructed in weathered soil and rock, representing typical ground condition of Korea, has been analysed. The study includes ground settlement trough, pile settlement, axial forces and shear stresses on the pile. In particular, the change of apparent pile capacity related to the tunnel advancement based on the load-settlement relation has been analysed. The numerical modelling results show that the settlement trough might not be represented by the well-known Gaussian distribution. Due to the reductions in vertical stress below the pile tip and settlement of the surrounding ground, pile settlement was induced, thereby changing shear transfer mechanism at the pile-soil interface. Some insights into the pile behaviour under the influence of tunnelling obtained from the numerical analyses will be reported and discussed.
