摘　　要：高海拔特重冰区特高压交流铁塔尺寸大、负荷重,塔型选择是否合理直接影响到铁塔受力的合理性和结构的安全性,现有的铁塔设计经验已不能满足要求。本文对典型耐张塔,包括干字型塔、酒杯型塔、门型塔以及分体塔的受力特点进行分析,按照3 000 m海拔的跳线间隙进行尺寸规划,对40 mm和60 mm特重冰区各型铁塔进行了建模计算,从经济性、地形适应性和节点构造难度等方面给出了推荐的塔型选择方案,为铁塔设计和工程建设提供参考。The size and load of UHV AC tower in the high altitud and extra heavy ice zone is large,so whether the tower type is reasonable or not directly affects the rationality of the force and the safety of the structure of the towers,and the existing tower design experience can’tmeet the requirements.In this paper,the mechanical characteristics of typical tension towers,including gan-type tower,cup-type tower,door-type tower and fission tower are analyzed,the size is planned according to the jumper clearance at 3000 m altitude,modeling and calculation of different type of towers in 40 mm and 60 mm extra heavy ice zone are carried out,the recommended tower type selection scheme is given from the aspects of economy,terrain adaptability and joint construction difficulty,the research results can provide reference for tower design and engineering construction.
