Suizhou River Bridge Cantilever Construction of PrestressedConcrete Continuous Box Beam

Tan Ming-ji

Abstract

Main methods Bridge of prestressed concrete continuous box girder construction are the overall support casting method,subsection cantilever construction method,and place cantilever method,and so on.Variable cross-section prestressed continuous box beam construction mainly adopts two methods: suspending and combining or cantilever construction,its construction technology is complicated comparing with the Equal Section beams.According to the practice the article expounds precisely variable cross-section prestressed continuous box beam cantilever construction method,and makes a comprehensive analysis of noticeable problems in the engineering construction.
