Abstract
Crossing above both the Nanchang-Jiujiang Intercity Railway and Beijing-Kowloon Railway, the main bridge of Gong’an Bridge is a continuous prestressed concrete girder bridge with the span arrangement of (70+125+70)meters. This thesis introduced how to select the bridge site and bridge type, how to design the bridge structure, how to select the calculation parameters, and how to erect the girder by swing method. Meanwhile, by using finite element software named Dr. Bridge, the bridge structure was calculated and analyzed longitudinally and transversely, and the results show that all the structural strengths, stresses, displacements, etc. can accord with the relevant provisions of the design codes.关键词
