摘　　要：着重研究输电杆塔由于杆身自重横担及铁附件等纵向力的作用下 ,使杆身产生纵向变形进而产生纵向弯矩。这就要对杆塔在整立过程中吊点的选择进行修订。Pole for electric power lines has changed its deformation during it was lifted up as a whole.It is a vertical deformation as the pole has dead weight,ect.The vertical deformation leads to the moment of vertical force.So ceiling spots must be revised.

关 键 词：输电杆塔 附件 纵向力 纵向变形 吊点 弯矩 自重
