Zusammenfassung:The present invention relates to a method for restoring abutment lateral deformation of a bridge, more specifically, to estimate the required hydraulic pressure required for abutment restoration, to examine the safety of the abutment, the girder and the hydraulic plate. A hydraulic operation means is installed between abutments and girders, which are necessary positions for securing a laying gap. After the measuring means is installed on the abutment and girders, the oil pressure is gradually increased while the opposite laying gap is fixed. The abutment lateral deformation restoration method uses the axial stiffness of the girder and the self weight of the upper structure and the opposite abutment, in order to stably restore the abutment lateral deformation by vertically erecting the abutment. 본 발명은 교량의 교대 측방변형 복원 공법에 관한 것으로서, 상세하게는 교대의 복원에 필요한 소요 유압력을 산정하고, 교대와 거더 및 유압 플레이트의 안전성을 검토한 다음, 교대의 뒷채움재를 제거한 후, 유간 확보가 필요로 하는 위치인 교대와 거더 사이에 유압 작동 수단을 설치하고, 교대 및 거더에 계측 수단을 설치한 후 반대편 유간을 고정시킨 상태에서 유압력을 서서히 증대시키면서 압력과 변위를 계측하면서 안정적으로 교대를 수직으로 직립시킴으로써 교대의 측방변형을 안정적으로 복원하도록 하는 거더 축방향 강성과 상부구조물 자중 및 반대편 교대를 이용한 교대 측방변형 복원 공법에 관한 것이다.
