摘　　要：为探讨输电塔中螺孔间隙对结构变形的影响程度,以ZMP2-60直线猫头塔为例,采用有限元分析软件ANSYS建立了不考虑和考虑螺孔间隙的输电塔模型,通过分析输电塔在风荷载作用下的位移发现,0°风向时螺孔间隙对ZMP2-60输电塔的变形影响最大。For study of the impact of bolt gap on the deformation of transmission tower, taking the ZMP2-60 transmission tower for an example, finite element analysis software ANSYS is used to establish two models of transmission tower for considering bolt gap or not. Through analysis of deformation of transmission tower under the action of wind load, it finds out that the holt gap has greatest impact on ZMP2-60 transmission tower in the wind direction of 0°.
