Summary of contents
The paper is the design of Ou Chi Bridge in Zhuzikou. According to a requirement of design and the regulation of specifications for highway bridge design,by primary selection, The design put forward three programs that are the prestressed concrete continuous girder bridge, arch, concrete T-girder simple supported beam-bridge than the election. Than after the election, concrete T-girder simply supported beam-bridge as a programs recommended.
The paper, First carry on bridge-program selection,the second carry on the main bridge to the overall structural design, and then the upper part of the structure of the internal forces, reinforced the calculation and checking, the final structure of the lower part of the calculation and checking.
This paper, in accordance with the requirements of design, there is a more detailed design and calculation process, arrive at accurate conclusions, rendering the working drawings, with the design tasks.
