Supporting structure used for supporting main body structure of tie bar arch bridge

The invention discloses a supporting structure used for supporting a main body structure of a tie bar arch bridge. The supporting structure comprises a supporting frame arranged at the outer side of apier, and a plurality of limiting structures which are arranged on the supporting frame, and are used for supporting the main body structure of the tie bar arch bridge. The supporting structure has the beneficial effects that: the supporting frame at the outer side of the pier is taken as a force bearing structure, the main body structure of the tie bar arch bridge is lifted to a position near amounting position, the main body structure is conveniently positioned; during construction, action of regulating the position of the main body structure is reduced, and positioning and mounting efficiency is favorably improved; and the supporting frame is arranged at the outer side of the prier, and a bearing table supporting the pier can be taken as a mounting base of the supporting frame, so that stability of the main bo
