PROBLEM TO BE SOLVED: To provide a repairing structure for an existing bearing apparatus, which is implemented by using an existing base plate and anchor bolts, need not secure a high under-girder installation space, and is free from a fear of interference with a jack-up space in a bridge axial direction, and to provide a repairing method for the existing bearing apparatus. SOLUTION: In implementation of the repairing structure for the existing bearing apparatus, a new base plate 9 is carried in from a direction at right angles to the bridge axis and fixed to the existing base plate 1 of the existing bearing apparatus. The new base plate has a bridge axial dimension smaller than an inner axial interval between a pair of the anchor bolts 3 which fix the existing base plate 1 at its ends in the direction at right angles to the bridge axis. Then a shear deformation restricting-cum-bearing member 12 is carried in from the direction at right angles to the bridge axis and fixed to the new base plate 9. The member 12 has a bridge axial dimension smaller than the inner axial interval between the pair of the anchor bolts 3. Further an elastic load bearing body 15 is set in the shear deformation binding member 12, and a superstructure 7 is borne by the elastic load bearing body 15. COPYRIGHT: (C)2005,JPO&NCIPI
