In view of the problems of bridges in service such as more attention to construction, less to maintenance and unsmooth information transmission, the establishment of maintenance management platform based on BIM technology has become a new direction of bridge maintenance management. In this paper, taking large-scale bridge in Wuhan as an example, BIM model used in design, construction, management and maintenance, a large-scale bridge maintenance management platform was built through taking advantages of BIM information processing with integration of new technologies such as GIS, mobile internet, IOT and so on. Practice has proved that the platform can effectively improve the management efficiency and scientific decision-making level of large-scale bridge maintenance, realize the digitalization and intelligentization of large-scale bridge maintenance management, and provide a new method for the management and maintenance of large-scale bridges throughout the life cycle.
