Zhuzhou rocky bridge preliminary design for construction of a simply-supported (turn) continuous beamPick toThis design is mainly zhuzhou bozez, preliminary design of the structure of the bridge. Zhuzhou rocky bridge using simply-supported turn construction method of continuous girder hoisting, prefabricated after construction, then into supported beam cast-in-situ dismantle temporary pedestal, formed by the continuous girder girder altitude box girder, span of 30 meters.The design of the first chapter 11 points, the introduction, this paper describes the project for the surrounding environment, the bad design requirements, construction methods, The second chapter for bridge and longitudinal and transverse layout, The third chapter for section geometry, DiSiWuLiu chapter for internal force calculation and internal combination times, Chapter 7 for prestressing tendons estimation, layout, DiBaJiu chapter for loss of prestress and internal force calculation after reinforcement, Chapter 10 of intensity for deck. Chapter 11 for stress, deformation and other computations.Keywords: prestressed concrete continuous girder bridge construction in turn for internal force combined times advance arch
