| Abstract: | The main bridge of Wuhan Tianxingzhou Changjiang River Rail-cum-Road Bridge is a double pylon and triple cable plane steel truss cable-stayed bridge with span arrangement(98 196 504 196 98) m.The main girder of the bridge is a composite girder made up of three main steel trusses and concrete slabs.On the upper deck of the bridge,six-lane roadway is arranged while on the lower deck,the double-track passenger dedicated railway,the Grade I double-track railway,is set.Of the overall main bridge,the railway deck is designed as a concrete slab composite ballast deck formed by longitudinal and transverse girder system.In this paper,the structural design and testing methods for the test models of the concrete slab composite railway floor system are presented. |
