Design for Qinglonghe bridge
Abstract
This design focuses on the development of Huaiyang II bridge design, including the upper detail construction and dimensions of superstructure and lower structure.. The bridge is a （60+100+60）m three span prestressed concrete continuous beam bridge. The cross section of the main girder with variable cross-section is single box and double chamber. Firstly, the specific dimensions of the components are designed; and structural analysis is carried out inculuding dead load, live load, temperature load and prestress; then on the basis of the calculation of the internal force of the structure, the load combination and the checking computation of structural are carried out according to the specifications. The design strictly follows the bridge design specifications and design process, in line with the design requirements and specifications.
Key Words: Prestressed concrete continuous beam bridge；Structural design；Check
