| Abstract: | Relationship between forces born by bridge and rail under the action of temperature variation, deflection and braking are analysed by using brldge-ballast-rail as an unified model, and simply-supported bridges,30 m and 40 m in span length, are calculated with a programme of finite element of two-dimensional frame structure. |
| Keywords: | high -speed railway simply -supported bridge temperature variation deflection unified model |
