| Abstract: | The track structure is simplified as the elastically supported grillage girder. A space model of the track on roadbed - bridge transition section is established. The structure of the track on roadbed-bridge transition section is analyzed with the finite element analysis software ANSYS. The distribution of stress and displacement near the transition section are discussed for different stiffness ratios. |

| Keywords: | transition section stiffness ratio finite element analysis |
