Method for reinforcing simply-supported plate or simply-supported beam bridge
The invention discloses a method for reinforcing a simply-supported plate or simply-supported beam bridge, and belongs to the field of bridge engineering. The method includes the steps that skewbacks are arranged on the two side faces of an abutment of a span needing to be reinforced, and attached to the abutment, and the skewbacks and the abutment form a whole; arch ribs are arranged below the portion, of the span needing to be reinforced, of plate beams, the arc ribs and the bottom of the bridge form a whole on the middle section of the plate beams, the two ends of each arch rib abut against the skewbacks on the abutment, and the two ends of each arch rib and the skewbacks form a whole; transverse linkage beams are arranged on the bottom face, of the span needing to be reinforced, of the plate beams, the direction of the transverse linkage beams is perpendicular to the length direction of the plate beams, the transverse linkage beams and the bottom face of the bridge form a whole, and the transverse linkage beams and the arch ribs also form a whole. In the way, simple plate beam load carrying is changed into plate and arch composite structure load carrying, and the bearing force and the rigidity of an original structure are greatly improved. The method has the better reinforcing effect compared with reinforcing methods such as plate adhesion.
