Short term three dimensional back-analysis of the One New Change basement in London

This paper presents the results of a three dimensional back-analysis in the short term with the aim to validate the soil parameters used in the BRICK model. The comparison has been made between the results of the numerical analysis and the field measurements obtained on site during the works. An additional comparison between detailed modelling and simplified sequences is presented. Finally a LS-DYNA tool to model bearing piles as embedded beams using beam elements is presented. The results of this work have provided increased confidence in the new BRICK model parameters. Furthermore, the conclusions and lessons learnt in using the new system of pile modelling, as well as the construction sequence used, provide valuable information for their application in future projects and research work.
