A Review of Digital Twin Technology Applications in Railway Engineering
In order to promote the application of digital twin technology in railway engineering,this paper summarizes academic research papers on digital twin technology in the field of engineering construction at home and abroad,using literature statistical analysis and literature content analysis as the main research methods.The purpose is to provide a reference for the application of digital twins in railway engineering and analyze the current status of digital twin technology in various stages of railway engineering.The results show that digital twin technology has been extensively studied in large-scale engineering construction fields such as architecture,water conservancy,and electric power,which can provide a certain reference for the application of digital twin technology in railway engineering.The application of digital twin technology in the design stage of railway engineering covers model construction,station design,collaborative design,platform design,etc.In the construction stage,it mainly focuses on bridge and tunnel construction,railway data application,intelligent equipment,etc.In the operation and maintenance stage,it mainly includes intelligent operation and maintenance of stations,railway infrastructure operation and maintenance,railway communication operation and maintenance,railway data operation and maintenance,etc.Although digital twin technology has been widely used in the field of railway engineering,most related work is still in the initial stage of exploration,lacking extensive experimental verification and in-depth practice.To accelerate the development of digital twin technology in railway engineering,future research must continue to deepen,continuously carry out practical applications,verify the technical feasibility,and explore its wider range of application scenarios.
