Performance of pile due to tunneling-induced soil movements

Abstract

Tunneling would inevitably induce vertical and lateral soil movements on piles supporting adjacent buildings. In the present study, centrifuge model tests were conducted to evaluate the free-field soil movements due to tunneling and the effects of soil movements on a free-head single pile located nearby. Three-dimensional finite element analysis was also performed to back-analyze the centrifuge test data. The measured and predicted pile responses due to tunneling show fair agreement in both short-term (immediately after tunnel excavation) and long-term. © 2007 Taylor & Francis Group.
