I used to is a prestressedconcrete simply supported hollow slab bridge. Its main characteristics：Under the action ofvertical load, the bearing only produce vertical reaction, and no horizontal force. Flexiblestructure sculpt, small building height maintenance quantity is little, experience,thedomestic advanced level,Using precast hollow slab artifacts, shipped to the constructionsite, adopting cast-in-place concrete, connect the hollow slab, its characteristic appearanceis simple and easy fabrication, good integrity.To complete the whole the design of the bridge, must put it into the upper structureand lower structure calculation of two parts.In the upper structure calculation,I finished thecalculation, the estimation of prestressed reinforcement effect and arrangement, calculationof bearing capacity limit state,loss of prestress calculation, calculation and deformationcalculation serviceability limit states of persistent and transient state stress check.Andcarries on the reinforcement and calculation, the comparison standard after all meet therequirements.In the lower structural calculation,must first determine the bridge pier, the pier, thesize of the drilled pile,then calculate capping beam, pier column, drilled pile internalforce,in this case and reinforcement calculation, after check specification are all meet therequirements.Through this graduation design, making me and start the initial stage in theformation of bridge engineering how to use learned knowledge for a comprehensiveunderstanding and operation of many software get exercise, wade for the future and lay agood foundation for entering the industry.
Keywords: simply supported beam; reinforced concrete structure;bored pile;thecalculation of reinforcement
