输电铁塔灾后性能评估及加固模拟

Post Disaster Performance Evaluation and Reinforcement Simulation of Transmission Towers

本文对阜鹤500 kV输电线路66#号的基础采用了连梁和高压注浆加固措施,对铁塔的损伤杆件进行了十字截面加固,对加固前和加固后铁塔的力学性能进行了评估,并对其在正常运行状态下进行了连续的变形监测,铁塔处于稳定状态。本文中对输电铁塔构件采用的快速无损加固方法已加固后铁塔的性能评估方法可以为后续的工程提供工程经验。

In this paper,we adopt connecting beams and high-voltage grouting to reinforce the 66#foundation in Fuxin-Hexiang 500 kV transmission Lines.We use cross-section to reinforce the damaged members of the of the tower.After the reinforcement,we evaluate the mechanical properties of the tower and continuously monitor the deformation of the tower.The result indicate that the tower is stable.The rapid and non-destructive reinforcement methods and the properties evaluation methods for reinforced towers,can provide engineering experience for other towers.
