摘要
泰州长江大桥是江苏省内跨越长江的又一座重要桥梁,采用三塔两跨地锚式悬索结构,跨径2×1080 m,为世界上同类桥梁之最。钢箱梁设计是全桥设计的重要组成部分,通过采用计算机辅助工程(CAE)的有限元计算方法,使钢箱梁的各主要部位做到受力合理,与此同时材料用量达到最佳。经过精心设计,最终泰州长江大桥钢箱梁材料指标为425 kg/m2。
Taizhou Bridge on Changjiang river is an important ground anchor suspension bridge with 2 ×1080m span in Jiangsu province. It is the largest three-tower two-span bridge in the world. The design of the steel box girders is an important part of the project. The structure was deigned by finite element analysis of Computer Aided Engineering. Thus, the valid design and best steel dosage were obtained. Eventually the steel indicator of the girders is 425 kg/m2.
