| 摘 要： | 参照国内外已建成的各种同塔双回及单回紧凑型塔型资料,提出750kV同塔双回及单回紧凑型杆塔方案。针对该方案,分别从高强角钢及钢管构件两大方面进行了结构计算及经济性分析,并建议:750kV同塔双回紧凑型杆塔采用高强钢,单回紧凑型杆塔是否采用高强钢则需依据综合经济性而定;750kV同塔双回紧凑型杆塔主材采用Q345钢管构件,但单回紧凑型杆塔不建议采用;上述2种杆塔采用Q420钢管构件的经济性更为显著,但还需深入开展构件及节点构造等方面的试验研究。

| Abstract: | By consulting domestic and foreign compact double-and single-circuit tower designs,a design for compact 750 kV double-and single-circuit towers is proposed.Aiming to this design,structural calculation and economic analysis are performed in two aspects,including high strength angle steel and steel tube members.It is suggested that high strength steel must be used in compact 750 kV towers,while its application in compact single-circuit tower depends on economy;Q345 steel tube members are used as main structur... |
