摘　　要：基于有限元分析软件ANSYS构建了220 kV双回路紧凑型转角塔的梁桁混合模型,并对模型进行了静力分析,获得了输电塔架在最危险工况下的受力和位移状态,比较了模型计算结果与真型塔试验数据。结果表明,该模型可较好模拟铁塔试验真实受力情况,验证了铁塔设计的合理性与安全可靠性,为紧凑型输电铁塔优化设计及在线路走廊拥挤地区推广应用奠定了基础。The spatial three-dimensional truss-beam model of the 220kV compact transmission tower Is esta^nsnea ~y using ANSYS finite element analysis software. The static analysis of model is implemented and the force and displacement status is calculated in the control condition. Comparison of model experiment with prototype tower test, the results show that finite element model can well simulate the force state of tower test and it verifies that the design of tower is reasona- ble, safety and reliability. Thus, it provides foundation for the further optimize of transmission tower and the application in the line corridors crowded area.
