| 摘 要： | 设计时间较早的塔型没有考虑风压高度变化系数，最大设计风速偏低。对原有铁塔进行加固补强，提高其抵抗大风的能力，保证铁塔的安全运行迫不及待。通过试验对背靠背主材加固措施进行探讨，考虑连接板形式以及连接螺栓个数对加固后承载力的影响，在试验的基础上提出加固优化方案，为同类塔型的加固补强提供参考

| Abstract: | Some typical towers often occur collapse in transmission line, which is designed early. The lower maximum design wind speed and without considering the height variation factor of wind pressure are the main reasons of tower collapse accident. It is a pressing question to resisting the strong wind by reinforcing and strengthening the tower. The reinforcement and strengthening method of back to back on leg members are researched through the experiments. The optimization solution is proposed by considering the influence of bearing capacity on the type of connecting plate and bolt quantity. The optimization solution can provide reference for reinforcement and strengthening of transmission towers. |
