PROBLEM TO BE SOLVED: To provide a precast prestressed concrete web for a concrete box girder bridge which is high in durability, relatively low in maintenance cost, production cost, and construction cost, and excellent in aesthetic appearance, and to provide the concrete box girder using the precast prestressed concrete web.;SOLUTION: In the precast prestressed concrete web for constructing the concrete box girder bridge, a plurality of vertically extending prestressing steels are arranged at predetermined intervals in a bridge axial direction in the web, and the prestressing steels are vertically prestressed. The web has two surfaces, and one of the surfaces is a corrugated surface having ridge portions and valley portions alternately arranged in the bridge axial direction in cross section, while the other surface is a flat surface.;COPYRIGHT: (C)2005,JPO&NCIPI
