摘　　要：晋东南—南阳—荆门1000kV特高压交流试验示范工程于2008年底建成。在工程建设过程中出现了铁塔变形问题。从现场调查、理论分析、真型试验等3个方面对曲臂及K节点变形进行了研究。研究表明,曲臂K节点发生位移是正常的,K节点是安全可靠的。针对铁塔变形问题提出了一些建议,可供以后工程参考。The 1 000 kV Jindongnan-Nanyang-Jingmen UHV AC Demonstration Project was completed at the end of 2008. Tower deformation occurred during construction. A study was conducted on the deformation of ＇K＇ joint and bend arm through spot investigation, theoretical analysis, and real model tests. It was proved that the ＇K＇ joint is normal in displacement and reliable in safety. Some suggestions are put forward against the deformation of transmission towers.
