Abstract: The existing structural damage identification methods were separated into the damage identification method of railway bridge machines and of other structures in this research.This classification was intended to analyzing the effects and the limitations of existing damage identification methods which were widely used in testing the railway bridge erecting machines.The prospects for development of the prospect of damage identification method of railway bridge girder erecting machines was put forward according to the characteristics of the practical application of railway bridge machines in damage identification.It is a researching direction that the damage identification method uses deflection influence line of displacement curvature which is based on the actual working conditions of railway bridge erecting machines.

Key words: railway bridge erecting, damage identification, working condition, influence line of displacement
