A new reinforced concrete filled GFRP tube structure is proposed, and its feasibility in the application of transmission lines in urban areas is analyzed by ANSYS finite element analysis and technical-economic com-parison. The results show that the structure can make up for the defects when the self-reliance lever of traditional material transmission lines is under high load, and improve the safety operation level of the circuit, reduce the construction difficulty, thus having a certain feasibility in the application of transmission lines in urban areas. Additionally, the paper maintains that such key technical problems as connection and material ageing should be solved before GFRP tube reinforced concrete structures are applied in urban transmission lines.%提出了一种新型的GFRP管钢筋混凝土结构，通过ANSYS有限元分析、技术经济比较分析，对其在城区输电线路上的应用进行了可行性研究。结果表明，该结构能弥补传统材料输电线路自立杆在承受较大荷载时的众多缺陷，并提高线路安全运行等级，降低施工难度，在城区输电线路中应用具有一定的可行性。作者还提出了GFRP 管钢筋混凝土结构在城区输电线路中推广应用需解决连接问题与材料老化等关键技术问题。
