Construction Monitoring of Prestressed Concrete Continuous Beam Bridge

Abstract:

The creep of concrete structure has a prodigious effect on bridge alignments and the stress control during the bridge construction. In the meantime, the problems such as pre-stress losses, bearing asymmetry sink ,the concrete box-beam deflection, box-beam web cracks, structure stress redistributing and so on, which make the bridge structure lose functions or even invalid early when it works. For these reasons, the construction monitor of the deformation and the long-term deflection of long-span bridges with high piers have important practical significance. Construction monitoring of prestressed concrete continuous beam bridge - new Tongyang canal bridge which adopt cantilever construction work is made.
