An investigation was conducted on the behavior of a piled raft on a rock slope having asymmetric geometry, through field measurement analysis. The contact pressure of the raft on the ground and the axial load distributions of the piles were measured using pressure cells and strain gauges, respectively. The measured data were analyzed to determine the contribution ratios of raft and piles, the distributions of contact pressure and pile carrying loads, and the axial load distribution of the piles. The contribution load ratio of the raft to the sum of the raft and the pile loads increased from 7.8% to 14.7% as the total bearing load of the piled raft increased during the construction process. It was also found that the asymmetric geometry significantly influenced the distribution of contact pressure and pile loads. The axial load distribution of the piles was dependent on the position of the pile in the raft and the geometry of the rock slope.
