First, make a parison and a decision of bridge schemes. According to the actual situation of the location of the bridge and the design requirements, preliminary two schemes are worked out including a simply supported：Continuous girder bridge and Arch bridge. Considered the security, the economy, the practical applicability and the beauty, a design scheme is chosen eventually after the pariasion. The Continuous girder bridge the appearance of which is arch bridge with hanging girder is chosen as the final bridge scheme. The final bridge scheme has been decided. First, the main dimensions and the detail size of the bridge structure need to be formulated bined previous design experience, specification, and the information of the bridges that have been built to calculate the structure for the next step. Secondly, calculate the upper structure including the beam and the box girder. Learn how to use Midas and build the model of the main part of the bridge by Midas to calculate the upper structure of the bridge. Configurate the mon mechanical reinforcement and the distribution reinforcement according to the internal force of upper structure calculated, and input the reinforcement configuratied to the model establish by Midas. Finally, the checking calculation of crack width, strength and rigidity is done to the bridge which has been matched the reinforcement well. Calculate the bottom structure after the pletion of the upper structure calculation. The bottom structural calculation is mainly about the cap and pile foundation, including the decision of the size, reinforcement design and checking calculation of strength of the cap and pile foundation. The pile which has been given reinforcement need to be considered the bearing capacity under E2 earthquake force whether meet the specification requirements. Finally, summarize this graduate design.
