• Closure Technique for Hybrid Girder Cable-Stayed Edong Bridge, China
  Abstract: Based on Edong Yangtze River Bridge, the second longest hybrid girder cable-stayed bridge with 926 m long main span, the influencing factors and crucial techniques of the main span closure method for long span hybrid girder cable-stayed bridge are studied. According to theoretical analysis, numerical evaluation and practical test, the loading assistant closure method with better thermal adaptability and less influence on bridge line and the forced status is employed in Edong Yangtze River Bridge in order to meet the requirements of the unstressed state control method. Based on the mentioned advantages, the loading assistant closure method is applicable to long span hybrid girder cable-stayed bridges. The conclusion can provide a reference for the further design of the similar bridges.

• Design and Construction of Steel Box Girder for Jiashao Bridge, China
  Abstract: The main navigation bridge for Jiashao Bridge is a steel box girder, six-single-pylon, four-plane cable stayed bridge with span arrangement of 70+200+5¡Á428+200+70=2680m. It is the largest multi-pylon cable stayed bridge worldwide currently with steel box girder width of 55.6m, total bridge length of 2680m, the longest longitudinal slope for bridge deck of 0.45%, and total steel consumption of 77,000 ton. The main characteristics for separated carriage box girder structure are: the width of one carriage is more wider which reaches 24m; the distance between left and right carriages is bigger which reaches 9.8m; the four cable planes make left and right carriages have a relatively independent loads carrying state; rigid hinges are used in span middle of the whole bridge. This paper introduces the design and construction for steel box girder of Jiashao Bridge, including the erection of girder segments in no cable area, cantilevered assembling erection of four-plane steel box girder, and the closure plan for steel box girder of multi-pylon cable stayed bridge.

• Application of Innovative Technology in Baling River Bridge Design, China
  Abstract: Baling River Bridge is the longest span steel truss girder suspension bridge in China. This bridge crosses valleys in mountainous zone of west China where mountains are high and slopes are steep. The clearance between the bridge deck and valley bottom is approximately 370m without water under the bridge, which brought about a number of difficult issues to the construction of both superstructure and substructure. This article introduces how a number of innovations in the design technologies had been developed in the course of design of Guizhou Baling River Bridge on the bases of the bridge construction conditions and the implementation of ¡°safe, applicable, economical and aesthetically pleasing¡± design philosophies for the reasonable determination on the proposed bridge type.

• Key Technology in Steel Box Girder Design of Huangpu South Branch Bridge, China
  Abstract: Huangpu South Branch Bridge is a single span steel box girder suspension bridge with main span length of 1108m. A series of key technologies have been used in the steel box girder design. According to the results from wind resistant test study the external shape of aerodynamic of main girder is optimized and the guide plate is arranged, which have improved wind resistant stability of main girder greatly. According to the statistics of regional vehicle loading and based on the analysis on fatigue life of steel deck surface plate by measures of increasing the thickness of top slab, adding transverse ribs between diaphragms the stress of top slab is reduced thus improving the fatigue life of steel bridge deck. An appropriate solution for pavement is prepared according to the local physical climate unique features and vehicular loading situations. The solution of protective coating against corrosion is determined by overall considering the construction method, coat life and cost. By 3D simulation analysis method the forces on main girder under various cases are analyzed. Those above key technologies are of reference value for designs of similar bridges.
