Application of bonded prestressing technique to large aqueduct and its control;

Construction technigue of 28.8 m span-beam by post-tensioning method with bonded prestress;

The large span beams adopt bonded prestress technology,and the floors adopt non-bonded prestress technology.

In order to reduce temperature impact on the structure and facilitate the construction,unbonded prestressed reinforcement was arranged at the first floor of basement.

The article,based on the typical project,mainly introduces the construction technology with post-tensioning and prestress with bond,discusses its construction experiences and puts forward some problems to notice.

It is,therefore,that a prestress with bond method has been adopted,which would be beneficial to its earthquake resistance.

The box section transfer beams are chosen,and the technique of prestressed concrete with bond is used.

Introduces the designing process and construction requirements of the gate beam of the Huaihai Food Town,which has a span of 40 meters,with the technology of partly prestressed concrete with bond.

Aiming at the quality question which possibly appears in bonded prestressed concrete structure,this paper proposes the pre-construction,under-construction and post-construction quality control points.

The bonded prestressed concrete structural wide flat beams were employed as the frame beams, while the unbonded prestressed concrete structure was applied to the junior beams.

This article according to bonded prestressed construction technology application、operation points and tension technical angle of a car show center,And a benefit analysis for this technology.
