Load and settlement behaviors of a numerical pile-raft foundation in soft soils after the consolidation are presented in this paper. Modified Cam Clay (MCC) model was adopted to model the soil behaviors. Three dimensional FEM analysis based on MIDAS-GTS program was conducted in the study. The influences of pile-to pile spacing distance and pile length as well as soil model parameters were monitored. It generally finds that the trend of the load distribution and settlements of piles and raft are dependent of these effects. A post consolidation analysis for a pile-raft foundation under the loads could be suggested for the long-term condition of the foundation.
