摘　　要：针对330 kV黄侯输电线路95号3A1-ZMC1型直线杆塔倾斜的现状,进行了地质、地貌取样及卫星云图对比,分析了A、B腿侧沉降严重的原因及塔身加装拉线保护、脚板加垫板、可调式联合大板基础等处理方法,结合线路运行现状,提出了塔身安装四方拉线、A腿塔脚板下方支垫楔形垫板的纠偏措施,解决了杆塔基础因土质原因造成的基础下沉倾斜隐患。实施后运行效果良好,并推广应用至同机理倾斜杆塔上,提高了设备的健康运行水平,为类似架空输电线路杆塔倾斜处理提供参考。Based on the investigation of the tilt status of NO. 95 3 A1-ZMC1 linear tower of the330 kV Huanghou transmission line,the geological and geomorphological sampling and satellite cloud chart analysis are carried out. The causes of the serious settlement of A & B legs are analyzed. The treatment schemes such as installing stay wire protection on the tower body,adding foot plate with base plate,adjustable combined large plate foundation and new displacement transformation are analyzed.Combined with the operation status of the line,the installation of the tower body is put forward. The measures for rectifying the deviation of the wedge-shaped base plate and A-leg tower,and the final treatment plan for the new displacement and transformation,solved the hidden danger of the sinking and inclination of the tower foundation caused by the soil quality,achieved good results after implementation,and was popularized and applied to the inclined tower of the same mechanism,improved the healthy operation level of the equipment,and provided a reference for the treatment of the inclination of the tower of the overhead transmission line.
