摘　　要：部分110~220 k V输电线路在运行过程中,铁塔塔腿经常出现严重腐蚀的情况,影响了杆塔的安全运行。为此,对铁塔塔腿腐蚀原因进行了剖析,对现场腐蚀样本进行形貌、EDS能谱、X射线衍射、元素分布等分析,进一步阐述了塔腿防腐失效的内在因素,并提出了相关防腐对策。Serious leg corrosion affecting operation safety of towers is quite common in the operation of some110？220 kVtransmissionlines.Therefore,the paper discusses the corrosion causes and analyzes the corrosion sampling through morphology,EDS energy spectrum,X-ray diffraction and element; besides, it expounds intrinsic factors of anti-corrosion failure of the tower leg and presents some countermeasures.
