| Abstract: | This paper presents the development and state of art of the prestressed concrete bridges in China. In recent years many prestressed concrete highway bridges in different types have been built in this country, such as simple supported girder bridges, balanced cantilever T-frame bridges, continuous girder bridges, continuous rigid frame bridges, cable-stayed bridges and composite arch bridges. The structural characteristics as well as the new techniques for design and construction of these bridges have been studied and discussed through some representations of each kind, in order to accumulate experiences for further development of the bridge engineering in China. |
