| Abstract: | Taking the end girder in road-bridge transitional section of double-slab ballastless track in Wuhan-Guangzhou passenger dedicated line for example,this paper calculates the bending moment of end girder and optimizes its reinforcing bars and dimension with passive earth pressure method and finite element method,and approves that end girders in Wuhan-Guangzhou passenger dedicated line are rational in dimension but the stressed reinforcing steel bars can be reduce properly. |

| Keywords: | ballastless track end girder passive earth pressure finite element method |
