description The invention relates to a negative reaction force control device of a bridge and a bridge structure, the negative reaction force control device comprises a bridge pier, a cross beam is mounted on the bridge pier, and a tension beam is fixed at the bottom of the cross beam; the distribution beam is supported on the tension beam; one end of the inhaul cable is fixed to the distribution beam, the other end of the inhaul cable is fixed to the pier, and pre-tensioning force is applied to the inhaul cable; the tension of the inhaul cable is transmitted to the tension beam through the distribution beam; the longitudinal restraining device is installed on the pier, and the longitudinal restraining device is fixed to the distribution beam and used for limiting the distribution beam to move in the longitudinal bridge direction. The influence of negative reaction force of the bridge can be eliminated, the usage amount of concrete is reduced, the cost is reduced, meanwhile, the longitudinal restraint device can limit lo
