In this study, the behavior characteristics of vertical and batter piles were analyzed by the model tests and the numerical analyses. Model steel pipe piles with the inclination of 0$^{circ}$, 10$^{circ}$, 20$^{circ}$ and 30$^{circ}$ were driven into sands with the relative density of 79%. The static compression load tests and numerical analyses using PENTAGON 3D were performed. The bearing capacities of batter piles with inclination of 10$^{circ}$, 20$^{circ}$ and 30$^{circ}$ were 111, 95, and 81% of those of vertical pile in model tests, and the results of numerical analyses were similar to those of model tests. The bearing capacities p.oposed by Petrasovits and Award (1968) were similar to those of model test in the inclination of 10$^{circ}$, but overestimated in the inclination of 20$^{circ}$ and 30$^{circ}$. The skin frictions and end bearing loads were the maximum in the inclination of 10$^{circ}$ and decreased with increasing the inclination angle.
