Abstract


In recent years, prestressed concrete continuous girder bridges turn into one of bridge types in a wide range of applications by virtue of excellent structural properties. prestressed concrete continuous girder bridges have many advantages such as small deformation, good stiffness, simple conservation. But more and more midspan deflection and cracking of bridge appear in making use of bridge. The main reasons are influence of shrinkage and creep in prestressing force loss and deflection.At the same time, difference of fold order affects fold precision and internal force.Base on a prestressed concrete continuous girder bridge, contrary to the problem of deflection, from the starting of shrinkage and creep, by changing of relative humidity load age and creep coefficient the paper analyses influence of shrinkage and creep in prestressed concrete continuous girder bridges. At the same time,it also talk over impact of fold order to linear of bridge.In this paper, the analysis is very useful to construction of prestressed concrete continuous girder bridges.
