Abstract

Abstract

A simple analytical two-stages method for determining the lateral displacement and internal forces of group piles caused by tunnelling is presented here. The analytical solution proposed by Logananthan and Poulos is used to estimate the free-field soil lateral displacement induced by tunnelling at the first stage. At the second stage, the pile is treated as a beam on elastic foundation based on Winkler model and the lateral displacement governing equation of single pile is formulated by composing the free-field soil lateral movement to the pile. Then it is computed the shielding effect due to pile-pile interaction of passive group piles using simpli fied Mindlin equation. Finally the response of passive group piles due to tunnelling is obtained. The result from present approach is compared with that from FEM and BEM, good agreement is obtained.
