摘　　要：苏通长江公路大桥索塔为世界上建成的最高桥塔。索塔锚固区采用钢混组合结构,其构造及受力机理复杂,结构耐久性问题需高度关注;300 m塔高使得结构对风和环境因素相当敏感;高塔施工的抗风安全尤为重要。从索塔锚固区设计、索塔形态控制、抗风安全3个方面介绍苏通大桥索塔工程设计与施工的关键技术。Sutong Bridge tower with 300.4 m is the highest one in the world. The tower anchor area uses the steel-concrete composite structure; its structure and the stress mechanism are complex, so it must be paid more attention to the structure durable issue. The 300 m height makes the tower quite sensitive to the environmental factors such as wind and temperature. The wind-resistance safety of tower in construction stage against the wind is important especially. In this paper, the design of composite structure is introduced . The key technologies of tower geometry control and wind resistance in construction stage are analyzed.
