| Abstract: | Due to the interaction between railway bridges and CWR, the longitudinal forces of CWR arepassed to the piers through the structure of the bridge. In this paper, the intensity of the piers is calculated and their safety reservation analyzed in order to guide and improve CWR design so as to increase safety and save cost. |

| Keywords: | longitudinal forces piers intensity safety reservation optimum design |
