Research on Digital Infrastructure Platform for Expressway Infrastructure Based on BIM+GIS
Highway engineering construction has a long construction period,multiple specialties,multiple types of data and information,and a low degree of structured basic information.To achieve the full cycle and multi factor digital construction of highways,it will inevitably face the integration,processing,and maintenance of massive data.Traditional information system architectures or manual management method cannot complete the relevant work,resulting in poor circulation and sharing of highway engineering data throughout the entire lifecycle,and difficulties in the integration and management of massive data.Traditional business digital constructions have poor systematization,and existing systems are mostly based on a specific business or work site,which makes it difficult for business data compatibility,standardization,and uniformity to support the transmission and application of the entire lifecycle.This article proposes a digital basic platform for highway infrastructure based on BIM+GIS.It aims to achieve basic data support for all elements,all stages,all businesses,and digital management applications of roads.As the foundation,it provides standardized road element data,application interfaces,2D/3D models of road facilities and equipment,high-precision maps,and other visual services and support for business systems such as construction management,maintenance,and operation.
