The invention provides a method for controlling wind vibration of an electric transmission line high tower, belonging to a new method for simultaneously controlling the bending wind vibration and the torsional wind vibration of an electric transmission iron tower. The method adopts a viscoelastic damper which is installed in parallel outside a main material of the iron tower for controlling the bending vibration; the method is different from the former method that the viscoelastic damper is installed in a steel tube, and the method is not limited to a steel tube tower but is also suitable for an angle steel tower; and the method adopts a tuned mass damper (TMD) which is installed in a position of a tower head or a cross arm of the iron tower for controlling the torsional vibration, and the method is different from the former method for controlling the bending vibration. The method can simultaneously control the bending vibration and the torsional vibration of the electric transmission pole and tower, has good control effect, convenient installation and maintenance and low cost, is suitable for both the steel tube tower and the angle steel tower and has no adverse effect on the stress performance of a pole and tower structure, and the elastic parameters and the damping parameters of the damper are adjustable.
