摘要：
With a small cross section, a light deadweight and a convenient replaceable tendon, externally prestressed bridges have many special traits compared with other bridges. With a practical case, this paper analyzes the design of externally prestressed steel box girder bridges, which contains the bridge span, beam construction, externally prestressed layout, substructure and construction programs. Through economic, social analysis, discusses the prospects for the application of external prestressing structure.
