The invention relates to a suspension bridge sling with a pneumatic control measure. One or more spiral lines are wound on the outer surface of the suspension bridge sling, and the winding direction of the spiral lines is the same as the original rotating direction of the sling. The distance between the spiral lines is an integral multiple of the lay length of the sling, the diameter of the spiral line is 0.02-0.2 times of the nominal diameter of the sling, and the spiral lines are made of complex fibers, steel wires, bundles of steel wires or other materials. According to the suspension bridge sling, the spiral lines wound on the surface of the sling further destroys the correlation of wind load along the axis direction of the sling, so that the wind loads received on different cross section of the sling at the same moment are different, and thus the overall wind load acting on the sling can be reduced. The winding technology of the spiral lines is simple, and only the existing production technology of steel wire ropes needs to be simply adjusted.
