The effect of retaining structures on the performance of raft foundations enhanced with deep foundation elements (typically piles), simply known as piled rafts, was examined numerically. Illustrative piled rafts were analyzed using a simplified, linear elastic, plane strain finite element model. The effect of the structure was evaluated on the displacement profile, differential displacement, raft bending moments, and pile butt load ratio. For fully piled rafts, the effect is minimal. However, for partially piled rafts, the effect can be significant. Details are given in dimensionless plots.
