摘　　要：泰州大桥钢中塔首次采用纵向人字型钢塔结构,制造安装难度大,通过对钢混结合段、整体式塔柱节段、下塔柱合龙段等不同结构形式的钢塔节段的特点开展针对性分析,提出不同的钢塔节段制造工艺方案,并通过泰州大桥实践,为今后采用高强厚钢板、结构形式复杂的钢塔柱制造提供了借鉴及技术保障。The central tower of Taizhou Bridge adopts the vertical steel tower structure for the first time in the world and its manufacturing and installation are also difficult.Through targeted analysis in the steel-concrete composite section,the integral segment,the lower link segment and different structural forms of the steel tower,we propose different manufacturing programs for different segments,and the application to Taizhou Bridge will provide references and technical support for using high-strength steel plate and manufacturing of the steel tower with complex structural forms.
