结合输电杆塔震害主要型式及其原因分析，分析了现有杆塔抗震验算范围对输电线路抗震能力的影响，并提出杆塔抗震验算范围调整的建议。基于静力法、反应谱法和时程分析法等计算方法对杆塔结构抗震验算的适应性，提出了不同杆塔结构抗震设计的推荐方法。

By the analysis of seismic hazards of transmission tower, the existing aseismic checking calculation range has effect on the aseismicity of transmission lines, and the range needs to be adjusted. The recommended methods for aseismic design of different transmission tower structure are provided based on static method, response spectrum method and time history method etc.
