By analyzing the bridge structure in the course of the dead load and live load, taking into account different load safety factor for load combinations that will limit state as a result of the combination of two kinds of forces calculated tendon force estimates, estimate the various sections of the steel beam, in accordance with certain requirements of the steel beam is a good layout, construction and consider re-simulate prestress for the role of the second combination, the process of the construction and use of a cross-sectional strength checking, stress and deformation checking checking.

Beam Edge

Prestressed concrete beam bridge cross-section using T-shaped cross-section. Anti-shrinkage reinforcement requirements adopted under the dense arrangement of all the memorial steel welds are double-sided welding, using a special form of prestressed reinforcement arranged in assembly is completed, tension on the deck to prevent the beam edge cracking.

For solving the big deflection problem which is cause by the far cantilever segment of dead load zero bending moment method, analyzing the composition process of dead load and prestress bending moment, and this paper presents the improvement of dead load zero bending moment method.The improved method adopts the prestress in principle: far segment more and close segment litter, which not only can insure the prestress bending moment bigger than dead load zero bending moment in all over the cantilever constructing stage, but also can control the deflection well. The improved method is applied to a PC continuous bridge which has a main span of 168 metres, the deflection decreases 37.4% to that of the original design.
