Abstract
In this paper, the development of a three-dimensional finite element model to back-analyse a case history on the response of pile foundation subjected to shield tunnelling is described. The case history is from the construction of the MRT North-East Line Contract 704 in Singapore. The FE model was created to back-analyse the behaviour of one of the instrumented pile group at Pier 20 where the full shield tunnelling process, including the application of face pressure, shield tunnel advancement, over-cutting, tail void closure and installation of lining was simulated. The effect of single tunnel advancement was simulated and discussed. Good agreement between the results from analysis and measured data was obtained which validated the FE model. © 2005 Taylor & Francis Group.
