保底线路抗台风加固技术研究

Research on the Reinforcement Technique for Typhoon-induced Disaster of the Reserved Transmission Tower-line

摘要: 探究了保底输电线路的抗风加固技术。基于台风彩虹数据，采用有限元方法开展输电杆塔内力分析计算，研究了强台风作用下输电杆塔的损伤特点，且进一步开展了输电杆塔抗台风加固技术研究，提出了主材、斜材和基础的加固方法，为输电杆塔的抗风防灾提供了参考。

Abstract: The wind-resistant reinforcement technique of the reserved transmission tower-line system is actively investigated in this study. Base on the data of typhoon "Rainbow" , Internal forces of transmission towers were computed by the aids of finite element method to study the damage properties of transmission towers which subjected to typhoon. Furthermore, the reinforcement techniques of the transmission tower were examined for major members, crew members and foundation respectively. The research can be taken as the reference for the wind-resistant design of transmission tower.
