摘要
Design for Changjiang river highway bridge A6 duplicate
box double room section concrete girder bridge
Abstract
The continuous beam bridge is a kind of bridge type used widely on the project. It not only has a reliable strength, stiffness and cracking, but also has a smooth journey comfortable, conservation work on the design and construction experience of the characteristics of maturity. According to the existing norms and commitments demands, the Changjiang river highway bridge program adjustments A6 were designed. This is a nine-span continuous bridge, whose cross-section is two-compartment, and changing on the road direction, constructed by pouring on-site on full framing. The first design includes constant load, the live load and the calculation of the internal forces. On the basis of a load combination, we can draw moment and shear envelope map. Next, according to the short-term effect combination disposition prestressed reinforcement, and carries on the loss of prestress the computation. Finally, carries on the checking calculation to this continuous bridge, whether to satisfy the design requirements. The design made detailed calculation mainly for the superstructure, and rough for substructure
Key Words: design;continuous bridge; full framing; prestress
