Method for resisting wind vibration of light large-span bridge surfaces by adopting damping cables
The invention relates to a method for resisting the wind vibration of light large-span bridge surfaces by adopting damping cables, and belongs to methods for improving the capability of resisting periodic force, such as wind vibration, of the bridge surfaces of hydraulic large-span cable-stayed or suspension bridges and the like. The method comprises a manufacturing method of a damping cable and a method for arranging the stretching end or the anchoring end of the damping cable. The method comprises the following steps: performing tension debugging; after the tension debugging, performing grouting from a grouting mouth so as to perform corrosion prevention on the cable; sealing the anchor by adopting high-performance rust-resistant concrete. The method has the advantages that the damping cables preventing the periodic force from causing vibration are arranged by utilizing the characteristics of the bridge surface, so that an additional structure of a bridge cannot be added; the structure function of resisting the wind vibration, of the bridge, can be realized by utilizing handrails of the bridge, so that the wind-vibration resisting capability of the bridge is improved, and besides, the sense of beauty of the bridge is increased.
