Abstract
Prestressed concrete box girder bridge with corrugated steel webs is a new type of bridge which uses corrugated steel webs to replace the traditional concrete webs. Compared with the traditional box girder bridge, it has certain advantages and has been widely used in bridge engineering. Combined with the characteristics of prestressed concrete box girder bridge with corrugated steel webs and reactive powder concrete theory, this paper puts forward the concept of new prestressed corrugated steel webs reactive powder concrete box girder bridge. By improving the material properties, structural design and construction methods of prestressed concrete composite structure with corrugated steel webs, its bearing capacity can be improved, so as to improve its construction efficiency and economic benefits. The research shows that the prestressed reactive powder concrete box girder with corrugated steel webs has the advantages of light structure and convenient construction, and has superior mechanical properties and obvious economic benefits when it bears the equivalent external load of prestressed corrugated steel web concrete composite girder.
