In order to investigate the effects of non-uniformity of subgrade stiffness on the concrete roadbeds, the stress and the surface displacement of concrete roadbeds for the slab track on the earth structure were evaluated by static FEM of three-dimensional. The results showed that on the non-uniform subgrade, the stresses and the displacements of concrete roadbeds were larger than those on the uniform subgrade. On the other hand, the stresses of steel reinforcing bars in the concrete roadbeds were smaller enough than fatigue strengths even on the non-uniform subgrade. It was confirmed that the concrete roadbeds have enough fatigue strength even on non-uniform subgrades.
