摘　　要：三峡右荆500 kV输电线路长江大跨越工程中的SZKT型大跨越铁塔,利用内悬浮外拉线抱杆与人字副抱杆有机结合的组合式抱杆,进行分解组立的施工方法,巧妙地解决了大跨越铁塔因头部横向尺寸宽、单吊重量大而造成的组塔施工困难。该施工方法以及人字副抱杆的安装、拆卸施工工艺,可供在建的1000kV交流特高压试验示范工程长横担铁塔组立施工借鉴。The SZKT large crossing tower used in the Yangtze River crossing of Three Gorges Youjing 500 kV transmission line project is constructed using combined lifting pole method, which combines guyed lifting pole and A-frame lifting pole. It solves tower construction difficulties caused by wide and heavy head of large crossing towers. This method as well as the A-frame erection and disassembling technology can be referenced for constructed wide head tower construction of the 1000 kV UHVAC demonstration project.
