Abstract: In this paper, we adopt connecting beams and high-voltage grouting to reinforce the 66# foundation in FuxinHexiang 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.
