摘　　要：文章探讨了角钢塔塔材的分类及其出现变形弯曲问题的原因,在此基础上提出一种测量角钢塔塔材弯曲变形的方法,通过采集变形塔材特征点空间位置信息,利用空间直角坐标系中点之间的几何关系,计算角钢塔塔材的弯曲变形值,为变形塔材的校正和维护提供数据支撑。This paper discusses the classification of angle steel tower materials and the causes for the bending deformation problems. On this basis, a method for measuring the bending deformation of angle steel tower materials is proposed. By collecting the spatial position information of the characteristic points of the deformed tower materials,and using the geometric relationship between the midpoints of the spatial rectangular coordinate system, the bending deformation value of the angle steel tower materials is calculated, which provides data support for the correction and maintenance of the deformed tower materials.
