摘　　要：为研究输电线路杆塔整体可靠度,引入等价描述方法来处理整体可靠度,定义了杆塔整体失效准则,运用可适用隐式功能函数的矩方法,对500 kV典型直线塔进行计算与分析,在"恒载加风荷载和恒载加覆冰加相应风荷载"工况下的可靠指标β分别为5.586和7.334。In order to study total reliability of power transmission line tower,equivalent description method was introduced to handle with the problem,total failure criterion for the tower was defined and moment method for implicit performance function was utilized for calculation and analysis on 500 kV typical direct line tower.Under the working condition of dead load adding wind load with dead load adding icing adding corresponding wind load,reliable index were respectively acquired as 5.586 and 7.334.
