针对某输电线路铁塔设计了地脚螺栓加固方案，采用新增辅助地脚螺栓的方法来弥补原地脚螺栓锚固强度不足的缺陷。应用有限元软件进行分析，结果表明地脚螺栓加固后上拔承载力有较大的提升，加固后地脚螺栓的破坏形式表现为靴板屈曲、地脚螺栓颈缩屈服。
Abstract：The anchor bolt reinforcement scheme is designed for a power transmission tower. The newly added auxiliary anchor bolts can make up for the defect of insufficient anchoring strength of the original anchor bolts. The finite element software is used for analysis,and the results show that the uplift bearing capacity of the anchor bolts has been significantly increased after reinforcement, and the damage forms of anchor bolts after reinforcement are boot plate buckling and anchor bolt neck shrinkage yielding.
