摘　　要：泰州大桥是世界上首座超千米的三塔两跨悬索桥,主跨为2×1 080 m,中塔采用纵向"人"字形、横向门式框架型钢塔,边塔采用门式框架型混凝土塔,加劲梁为扁平流线型钢箱梁结构,全桥共136片钢箱梁,总重约33 426 t。通过分析钢箱梁吊装顺序对结构体系和施工难度的影响,确定了三塔悬索桥合适的钢箱梁吊装顺序。Taizhou Bridge is the first three-tower two-span suspension bridge with spans over 1 000 m in the world. Its main spans are 2 × 1 080 m; the middle tower is a steel frame with longitudinal herringbone shape and lateral gate shape; the side towers are gate shaped concrete frames; the stiff girder consists of flat streamline steel box girders, with a total of 136 steel box girders of about 33 426 t for the whole bridge. This article determines the proper lifting sequence of steel box girders of this three-tower suspension bridge by analyzing the effect of steel box girders lifting sequence on structural system and difficulty in construction .
