Abstract
The design of super major bridges is of great representativeness applied to high-speed railway. Due to the multiple cross-line work-point, the complex plane and elevation relation of the line, the switch throat area and viaduct station on the bridge, and the complicated structural design, there remain huge potentials in perspective of special bridge structures and design innovations on super major bridges. This paper takes Tianjin super major bridge of Beijing-Shanghai high-speed railway as an example to briefly introduce the construction environment, main technical standards, geological conditions and the types of bridge piers and abutments of the bridge. Meanwhile, it also addresses the design features such as long-span continuous beams, turnout zone bridges, station platform beams, and focuses on the special structures of this bridge, and summarizes the experiences in the design of bridges on Beijing-Shanghai high-speed railway, which could provide references for future optimization and innovation of high-speed railway construction in China.关键词
