The invention provides a central buckle structure of a self-anchored suspension bridge, being characterized in that a plurality of pairs of rigid central buckles are arranged in the middle span, and each of which comprises a central buckle cable clip and a central buckle bar shaft; the central buckle cable clip is installed on the main cable; the central buckle bar shaft is welded or bolted by twoI-shaped steel bars; the two I-shaped steel bars are herringbone distributed; the upper end of the central buckle bar is connected with the central buckle cable clip; and the lower end of the centralbuckle bar shaft is connected with the main beam. By adjusting the slope and section size of each central buckle, the stiffness coordination of many pairs of rigid central buckles can be realized, and the combined central buckles with different slope and section can be formed, so that many pairs of central buckles can work together and share the unbalanced force between the main cable and the main beam equally. A self-anchored suspension bridge central buckle structure can effectively solve the bending unfavorable problem of the bottom of the main tower of a long-span self-anchored suspensionbridge and the slip problem of the main cable at the tower top.
