摘　　要：结合目前国内FRP复合材料杆塔的现状,依托灵州—绍兴±800 kV特高压直流输电线路工程,提出FRP复合材料转动横担的受力机理、设计方案,并通过塔线耦合模型进行仿真分析。分析结果表明:FRP复合材料转动横担通过在纵向不平衡张力作用下,发生转动,释放纵向不平衡张力,减小了横担及塔身的受力,可有效减轻塔重和基础混凝土用量,具有良好的经济效益和社会效益。Combined with the present status of the research and application of glass fiber reinforced plastic （FRP） tower, taking Lingzhou-Shaoxing ＋ 800 kV UHVDC transmission line engineering as research background, this paper put forward the force mechanism and designing scheme of FRP rotation cross arm, and carried out simulation analysis based on tower-line coupling model. The analysis results show that the rotation FRP cross arm turns freely under the longitudinal unbalanced tensions, so the longitudinal unbalanced tension can be released, the stress of FRP cross arm and tower can be reduced, and the weight of tower and the cubic amount of concrete foundation can be effectively reduced, which has good economic and social benefits.
