Based on a project of a 22+55+22m continuous composite box beam bridge made of prestressed Concrete, using influence matrix, Numerical Simulation and Iterative Algorithm, an adjusting method for suspender force of continuous beam arch combination bridge has been proposed. It uses Finite Element Numerical Model to calculate the influence matrix and Iterative Algorithm to calculate the suspender force. When rely on this project, the error could be under 0.05% through finite iterative algorithm. And the feasibility has been tested in the completed bridge. It turns out that the error of the measured suspender force of the completed bridge is smaller than that in the design.

Beam Bridge

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.
