This study focuses on the common wear phenomena on the side of the UB hanging plate of the suspension string clamp in the continuous stable wind area. The force models of the suspension string considering the wind load in three wind speed stages are established, and the formulas for calculating the gravity load and the wind load of the wire are developed, and the expression of the relationship between the contact point pressure (the contact point between the connecting angle steel and the deflected UB hanging plate) and the wind speed and the icing thickness is derived. The results show that the installation clearance between the connecting angle steel and the UB hanging plate is the main structural factor for the wear phenomena, and the side of the UB hanging plate will contact and wear with the connecting angle steel when the wind speed is greater than the critical wind speed. The contact force between the UB hanging plate and the connecting angle steel increases with the increase of the icing thickness, the span and the wind speed, and the influence of the icing thickness on this contact force is more obvious in the case of the occasion with large span and strong wind. This study evaluates the three factors of span, icing thickness and wind speed, which is of guiding significance for the structural optimization of the suspension string in the future.
