A bridge local damage identification method based on an influence line under a structure health monitoring system relates to the field of engineering structure health monitoring. The method comprises the following steps: (1) fast identification of a bridge influence line; (2) construction of influence line damage indexes; and (3) damage identification based on fusion of multi-sensor information. A bridge influence line is identified based on moving vehicles and bridge response monitored in real time by a bridge health monitoring system, the change of the influence line can be captured in a timelier and quicker way, and structure abnormality can be found early.
