Seminar - Jason Surjadinata - Analysis of Effects Of Tunnelling on Single Piles

Wednesday, May 25, 2005, 1.10 - 1.50 pm
Civil Engineering Lecture Room 3

Abstract

This presentation describes an efficient and practical method of analysis to predict some important effects of tunnelling on pile foundations. The method involves a combination of the finite and boundary element methods (FAB), with free-field ground movements predicted by the finite element method and the response of an embedded pile to these ground movements predicted by the boundary element method. A summary of the theory behind the proposed method, verification of the method and demonstration of its computational advantages and applicability are described. Predictions of the proposed method are presented for horizontal components of ground and pile displacements. Good agreement of these predictions with field observations has been obtained for a number of different cases, providing confidence in the utility of the method.

This presentation is going to be presented in the Fifth International Symposium TC28 Geotechnical Aspects of Underground Construction in Soft Ground on 16th of June 2005, Amsterdam, The Netherlands.
