2008 年，我国南方地区遭受冰灾，造成受灾线路杆塔大量损坏。通过研究受损铁塔的损坏情况，提出一种采用贴身拉线加固铁塔技术，拉线从挂线点起，经撑架撑离塔体，最后固结于塔脚。贴身拉线可利用塔脚充裕的抗拔力加固铁塔。

In 2008, the icing disaster in south China caused extensive damages to the transmission towers. Based on a study of damaged towers, a close wire-pulling tower-strengthening method was proposed. The pulling wire starts from the hanging point, passes through the supporting frame, and is finally fixed at the tower leg. The close pulling wire strengthens towers by utilizing the sufficient anti-pulling force of the tower legs.
