To mitigate the structural safety risks arising from various ailments in subway tunnels, this study leverages digital twin technology to establish an intelligent management system platform for subway tunnels. Through the design of an unmanned tunnel inspection vehicle, intelligent inspections of the tunnel are achieved. The study utilizes large-scale data analysis to promptly acquire and process information related to defects and deformations within the tunnel. By employing neural networks and machine learning methodologies, the Transformer model is utilized to achieve precise predictions of subsidence within the tunnel. Integrating various common supporting technologies, such as intelligent reconstruction of the subway tunnel environment, seamless data interconnection, perceptual interaction, and collaborative business strategies, this research establishes a subway tunnel full-node, multi-dimensional real-scene digital twin system. This system facilitates intelligent inspections, fault diagnosis, accurate subsidence predictions, intelligent interaction, and three-dimensional displays within the tunnel. Consequently, it significantly enhances the safety management and equipment maintenance efficiency of subway tunnels.
