Structurae

The Shanghai Yangtze River Bridge, which is 10 km long crossing the north Yangtze River Channel, is built to serve both highway and light-rail transit line. This paper describes the following three main problems: (1) The structure restriction system and the specialty of separate type steel box girder of the main navigation channel cable-stayed bridge. (2) The scheme conformation, structure characteristics and construction methods of the composite girder in deep water area, specially the optimization design of structure and construction step based on the condition that the whole span hoisting construction method should be used. (3) The security of light-rail train on a bridge serves both highway and light-rail transit line, mainly the feasibility and relevant research results on the problem that the light-railway is set on the cantilever of the girder.
