摘　　要：对1000kV同塔双回钢管塔典型节点的承载力影响因素进行研究,总结出钢管塔节点的合理的设计方法:合理的主管径厚比;支管相对于主管采用合理的角度;支管负偏心;节点板增设加劲板等,经过分析表明节点板增设加劲板的方法最为有效。This paper researches the influences factors of bearing capacity of 1 000 kV ultra-high voltage steel tube towers joint,concludes the design methods of steel tube joint,those are using the reasonable diameter-to-thickness ratio of the main tube,using the reasonable angle of the support tube,taking the negative eccentric in support tube,taking the stiffened plate in the gusset plate,the analysis illustrates that the last method is the most effective.
