摘　　要：以某猫头形高压输电塔为研究对象,基于概率可靠度的研究方法对其进行风灾易损性分析。通过计算,绘制输电塔处于不同破坏状态的风灾易损性曲线。通过对该塔两个方向上风灾易损性曲线的分析得出,结构作用效应和结构抗力的分布形态均服从对数正态分布规律,在强风作用下,该塔较易发生破坏。In this paper, a wind disaster vulnerability analysis of a cat-head-shaped transmission tower based on probability reliability was presented. The diagrams of the wind disaster vulnerability of the transmission tower iti different damage state were drawn. Based on the analysis of the wind disaster vulnerability of the transmission tower in two direction, it is clear that the structural response and the structural bearing capacity follow a log normal distribution. And the tower can easily be damaged by the strong wind.
