摘　　要：盐城广播电视塔在标高114.45m高空4个方向设置悬挑13.40m观光厅,观光厅通过空中环形走道连接。结构施工中利用标高114.45m钢结构+空中环形走道+预应力临时拉索形成的结构体系作为上部结构施工操作平台,省去脚手架的搭设,降低施工成本,既确保了施工阶段安全,又能保证工程质量。Four cantilever sightseeing halls with 13.40m length are set at altitude 114.45m in Yancheng Broadcast Television Tower,which are connected with ring walkway in the air.During construction,the combination structure with steel structures at altitude 114.45m,ring walkway in the air and temporary prestressed tensioning cable is used as operation platform for upper structures.This method can avoid the usage of scaffold and save construction cost to assure construction safety and engineering quality.
