摘　　要：1000kV晋东南—南阳—荆门特高压交流试验示范工程输电线路铁塔组立相对500 kV线路铁塔而言,具有高、大、重的特点,其组立施工难度更大。其铁塔型式主要有3种:猫头塔、酒杯塔、干字塔,每种塔型均有相应的特点,在组立施工时不能一概而论。在11标段组塔中采用了几种组塔方法,这几种方法各有特点,可以根据具体情况在特高压线路中加以应用。Compared to normal 500 kV counterparts, towers used in the 1 000 kV Jindongnan-Nanyang-Jingmen UHV AC Demonstration Line Project are much taller, bigger, and heavier, and more difficult to assemble and erect. There are 3 major types, namely, eat-head-shaped tower, cup- shaped tower, and ：1=-shaped towers, each having its own characters, which requires special attention in construction. Several tower assembly and erection methods are used in No.11 bidding section. Each method has its own characters and can be used in UHV lines according to specific circumstances.
