With the continuous development of urban infrastructure, utility tunnels serving as centralized conduits for underground pipelines now carry critical urban functions including power supply, telecommunications, and water distribution. Ensuring their safe operation has become a pivotal challenge in urban management. The security system based on digital twin technology provides intelligent safety solutions through real-time monitoring, data integration, and virtual-real interaction. By accurately replicating physical tunnels through digital twin models and enabling bidirectional interaction between virtual simulations and physical systems, this approach enables real-time risk alerts and precise hazard detection, significantly enhancing tunnel protection capabilities and response efficiency. This mechanism not only optimizes security management processes but also strengthens the resilience of urban infrastructure, driving the advancement of smart cities.
