采用湖南郴州王仙岭地区的一座500KV线路ZB。酒杯型直线塔的工程实际数据，采用空间桁架理论，在ANSYS中建立有限元模型，并验算输电塔塔架在其自重、覆冰荷栽，风荷载和导线张力的共同作用下塔架的承载能力。在不同的工况下得出输电塔塔架中相对薄弱的位置，薄弱位置在塔颈和塔身处，并对其进行优化设计。对比优化前后的输电塔塔架，承载能力得到很大提高。

Through the adoption of the engineering actual data of of a 500kv line ZB1 glass type linear tower in Wang Xianling Chenzhou Hunan province, based on space truss theory, establish finite element model in the finite element analysis software ANSYS, and calculate the bearing capac ity of the transmission tower in its weight, ice load, wind load and the tension of conduct and grounding line. Under different conditions determine the relatively weak position, the main weak links are in the neck of the tower and the body of the tower, and go into the optimization design. Com- pared with the bearing capacity of the transmission tower before and after optimization,it comes to a conclusion that its bearing capacity is greatly improved.
