Development Trend and Construction Techniques of Foreign PC Continuous Beam Bridges

The prestressed concrete(PC) continuous beam bridges have been playing a leading role in the construction of medium span,small span and commonly long span bridges and the vistas of development of the bridges is yet vast.In the recent several decades,though great achievements have been made in China in the construction of the PC continuous beam bridges,the global techniques of the bridges in the country in the filed of the design,construction and new material application remain to be further improved.The study of the development trend and construction techniques of foreign PC continuous beam bridges and the understanding of the advanced design concepts and construction techniques of the bridges can provide domestic enterprises with helpful reference for formulating their rational construction schemes in bidding foreign bridge projects and for reinforcing their competitive power in developing bridge construction markets abroad.
