Three-dimensional analyses of piled raft foundations subjected to ground movements induced by tunnelling

In an urban environment, many buildings are supported by pile foundations. Recently, the number of underground constructions nearby buildings is increasing. In this paper, three-dimensional analyses of pile foundations subjected to ground movements induced by tunnelling are carried out. Analyses are carried out for single piles, a pile group as well as a piled raft. The analysis results including deformations, bending moments, shear forces and axial forces along the piles are presented and compared.
