This invention is applicable to the technical filed of building engineering construction, and provides an incremental launching construction management method of a steel box girder. The method comprises the following steps: applying a calculation model of i-order natural vibration frequency to a viaduct pile foundation and a tunnel structure to perform vibration impact analysis; analyzing the stability of a high flasework of a bridge after a subway is constructed; judging whether the flasework structure meets the design requirement or not; when the vibration has little influence and the design of the flasework structure meets the requirement, modeling the box girders of the viaduct to form a building information management BIM model. By adopting the method, the BIM modeling is added into the incremental launching construction process; and thus, the information technology and the incremental launching construction of the steel box girder are integrated organically.
