摘　　要：随着我国国民经济的高速发展,土地需求不断增加,土地资源日益稀缺。受城乡规划及线路走廊制约,目前输电线路走廊选择日益困难,走廊清理难度不断增大。有鉴于此,试验复合横担结构代替传统的钢横担结构,不仅能够减小线路走廊宽度、降低走廊清理难度,同时还能降低塔高、节约塔材,从而取得良好的社会效益和经济效益。文章对复合横担在台风多发地区的应用开展研究,对复合横担杆塔进行技术分析,优化杆塔的塔头尺寸设计。With the rapid development of our national economy,the demand for land is increasing,and land resources are increasingly scarce.Restricted by urban and rural planning and line corridors,the selection of transmission line corridors is becoming more and more difficult,and corridor cleaning is becoming more and more difficult.In view of this,testing the composite cross-pole structure instead of the traditional steel cross-pole structure can not only reduce the width of the line corridor,reduce the difficulty of corridor cleaning,but also reduce the tower height and save tower materials,thus achieving good social and economic benefits.In this paper,the application of composite cross-load in typhoon-prone areas is studied,the technical analysis of the composite cross-load tower is carried out,and the head size design of the tower is optimized.
