Research and application of highway digital maintenance management platform based on BIM+WebGIS

As a kind of information management technology, BIM and WebGIS can provide strong support for three-dimensional model of structure, make people fully understand the specific state of structure, and solve the spatial problems maximally. This paper first discusses the characteristics of highway maintenance at present, puts forward the application of BIM+WebGIS integrated technology in the construction of highway maintenance management platform. Then, on the basis of introducing the overall framework of the platform, it focuses on the platform's three major systems: the integrated management system of highway production and maintenance, the safety management system of highway operation and the health monitoring system of bridge, are emphasized. Through the research of this technology system, the digital transformation of highway maintenance is realized, and the progress of highway maintenance management in the aspect of science and technology and intelligence is promoted, it provides reference experience for improving highway fine management by technical means.
