A Study On The General Design And Railway Floor System Of The Main Bridge Of Tianxingzhou Bridge

The main bridge of Tianxingzhou Bridge is designed as a cable-stayed bridge with a main span 504m, double pylons, three cable planes and three main truss. Based on the design of the main bridge of Tianxingzhou Bridge, the following aspects are studied in this paper.First, on the basis of sufficient study on the constructive condition of the main bridge of Tianxingzhou Bridge, different types of cross section of the steel truss beam, relationship between the length of steel beam node and quantity of steel, the shape of pylon, the form of anchorage and the structural system of the main bridge of Tianxingzhou Bridge are analysed. In this paper, the substructure of the main bridge of Tianxingzhou Bridge is also compared. Then, different forms of the floor system are studied, and the best sketch is investigated detaily under several load cases in this paper.The conclusion of this paper can be useful for the design, construct and monitorof the similar-typed bridges.
