| Abstract: | The conceptual consideration of bridge type for the main bridge of Xiushui Bridge on the Intercity Rail Transit from Jiujiang to Nanchang are described.Limited by the Transit alignment,the Bridge is required to be designed as a one with possible shallower girders.On the basis of the research and comparison of the bridge type alternatives,the steel box rigid-frame arch bridge with span arrangement(32 140 32) m is recommended for the main bridge of the Bridge in the design.In this paper,the overall design and structural analysis of the bridge are mainly dealt with. |
