Zusammenfassung:The invention relates to the technical field of in-service bridge moving load transverse transfer evaluation, and particularly discloses a bridge moving load transverse transfer evaluation method based on influence line rise and application, and the method comprises the following steps: (1) acting a moving load on a bridge, extracting an influence line formed by each beam under the action of the moving load, the influence lines can be strain influence lines, deflection influence lines or corner influence lines; (2) extracting the maximum value of the influence line at the midspan of each beam to form an influence line rise curve; and (3) comparing the rise change condition of each beam at the midspan through the influence line rise curve, and further evaluating the transverse distribution condition of the moving load so as to judge the health condition of the bridge. By establishing the evaluation method based on the influence of the linear rise on the transverse transfer of the moving load of the active-serv
