Midas Civil and Bridge Dr. Based Comparative Analysis for Continuous Beam Bridge Construction Monitoring

Single Column shaped bridge is often used as a city program, it has the separate grade crossing, and multi-entry multi-exit, and greater clearance under the bridge, etc. But its stress situation is more complex, for designers and construction workers, put forward higher requirements. This article embarks from the stress of single Column shaped bridge, comparative analysis shaped bridge and curved bridge, concreting continuous beam bridge differences and similarities, and proposes the support way to the heterogeneous bridge's influence. Based on the single column bridge study, we find a simplified method on modeling, and its accuracy is in line with requirements of project. Finally, analyzes of the actual bridge, verifies the correctness of the calculation method, and proposes the key technologies.

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.
