Countermeasures for midspan deformation of long-span prestressed concrete beam bridge

Because of bridge design theory,construction methods and new materials have been developed significantly in recent decades,the quantity and span of cable-stayed bridge growing fastly,the cable-stayed bridge gradually becomes a main type of the long-span bridge.

The paper presents an analysis of the cause for shear crack and deflection of long span prestressed concrete box-girder bridge.

Starting from the major technical indexes and structure of main bridge,the design and general construction scheme of upper structure are given,and the key technology for construction of extra-long-span continuous girder bridge is introduced as well,which provides precious experience for construction of similar bridge in the future.
