Abstract

Based on the analysis of the influence of prestressed beam tension on the concrete box girder structure, this paper puts forward the characteristics of the construction of viaduct. It is based on the construction characteristics of viaduct. The reasonable tensioning sequence of prestressed concrete box girder with the characteristics of viaduct construction has been put forward. To obtain the stress displacement value and the prestress loss value in the different tensile sequence, follow works have been done: The finite element software Midas/civil is used to establish the finite modal, and select the typical cross section has been select. Then, compared prestress loss of the prestressed concrete box girder in different steel beam tensioning sequence. Case 3 (abdominal - top - bottom) is the most reasonable.
