The invention discloses a bridge safety evaluation method and system based on big data, and belongs to the field of bridge safety supervision and prediction.The bridge safety evaluation method based on the big data comprises the following steps that all safety data of a bridge in the previous unit time are obtained; the safety data comprises bridge cracks, bridge load bearing, environmental parameters, bridge cable force and bridge deformation displacement; acquiring various safety data of the current bridge, and comparing the various safety data with the various safety data of the bridge in the previous unit time; acquiring information of vehicles passing through the actual bridge in unit time, and acquiring unit time average traffic loss of each safety data; compared with the prior art, the method has the beneficial effects that the safety and the residual safety time limit of the bridge are judged by acquiring the unit time average traffic loss of various safety data of the existing bridge and predicting t
