The normal operation of the tower is an important basis for ensuring the continuous power supply. The reliability of the structure of the power transmission tower as an important supporting device of the power transmission line must be ensured. On the one hand, in the process of use, the angle steel of the power transmission tower often suffers damage and deformation due to atmospheric corrosion, mechanical external force and insufficient design strength, etc. With the aggravation of the damage degree, the power transmission line will be collapsed and disconnected, causing the interruption of the power grid. On the other hand, the site investigation of the previous tower collapse accidents shows that the reasons for many tower collapse accidents are improper setting of the tower body cross section, instability of the oblique material and instability of the main material, etc. The in-service power transmission towers designed according to the previous specifications cannot meet the safety performance of the power transmission tower under the existing conditions. Therefore, it is necessary to reinforce the tower material of the power transmission tower.
