The piled raft (PR) system was developed to use the load-carrying capabilities of both shallow foundations (rafts) and deep foundations (piles). These components interact with each other through a complex soil-structure interaction scheme. The interaction effects affect the overall load response of PR. In this study, the explicit finite difference code FLAC3D (Fast lagrangian Analyses od Continua) was used to investigate the behavior of PR subjected to vertical loading. Several foundations embedded in soft clay were considered. The results prove that even in the case of soft clay, the load-carrying capacity of the raft and piles, when combined in a PR, becomes different from those of unpiled raft (UR) and group of piles (GP), due to the interactions between raft and piles.
