Research on Application of Digital Twin in Railway Construction

Abstract

AbstractCurrently, the construction industry is developing in the direction of digitization. From the planning stage to the operation and maintenance stage of construction projects, a series of digital-oriented practices have emerged. Among them, Building Information Modeling (BIM) shows great value in improving efficiency and saving costs. However, in the field of railway construction, BIM cannot fully meet the requirements of infrastructure management in some aspects. One of the requirements is to manage infrastructure data in a common environment. The emerging of Digital Twin (DT) has greatly promoted the digital transformation of the construction industry. The effective management of infrastructure needs to consider the needs of each stage, especially the operation and maintenance stage. The three-dimensional model is no longer just a digital model, but a digital copy of the infrastructure. The railway infrastructure needs to be expressed by a unique model throughout its full life cycle. This article discusses the application mode of digital twins in the construction industry, and proposes corresponding schemes for some typical application scenarios in railway construction projects, which can provide ideas for the application of digital twins in construction industry.KeywordsBIMDigital twinRailway engineeringInfrastructureFull life cycle
