description The invention discloses a bridge flexural rigidity damage identification method and system, and is applied to the technical field of bridge damage detection. Comprising the following steps: selecting a two-axle load vehicle, and parking the two-axle load vehicle at a midspan position of a bridge; the bridge is divided into a plurality of sections in the bridge length direction, the parking position of the two-axle-load vehicle is divided into a whole section, and the minimum division length of the parking section of the two-axle-load vehicle is the vehicle length; dividing the bridge into a plurality of sections; three displacement monitoring devices are arranged on each section, and deflection values of three points in each section are measured through the displacement monitoring devices; substituting the deflection value measured on each section into a flexural rigidity formula to obtain a real flexural rigidity value of each section; and calculating the real flexural rigidity value of each section, drawing
