Abstract

The paper describes state of the art non-linear analyses of the pile groups that were employed during the raising of the 133 m high triumphal arch which forms the centre piece of the new Wembley stadium in North London. The deformation behavior of these piles groups was critical during the lifting process, due to the slenderness of the arch structure. The issue was made more critical by the high profile nature of the project. The results of Class A (Lambe (1937)) predictions of the pile group movements are compared with observed displacements and rotations which were accurately measured to site. To illustrate the importance of soil non-linearity on pile group behavior, comparison is also made with pile group analyses which assume a linear soil stiffness
