Abstract：Addressing the shortcomings of timeliness and continuity in traditional underground railway monitoring technologies, this research, supported by a national key laboratory, proposes an innovative underground railway deformation monitoring and early warning technology based on the ultrasonic ranging principle. By establishing a comprehensive benchmark network and utilizing wireless transmission and internet technology, real-time data transmission and remote monitoring are achieved. The system comprises multiple subsystems including benchmark network establishment, data acquisition, data aggregation analysis, communication, and monitoring alerts, effectively resolving issues such as the high installation difficulty, cost, and maintenance inconvenience associated with traditional technologies. In comparison to traditional methods, this technology not only mitigates challenges in installation, high costs, and complex maintenance but also enables real-time and accurate monitoring of dynamic changes in underground railways, effectively preventing accidents. Furthermore, by simulating long-term track settlement curves, it provides crucial decision-making support for track maintenance and management. This research presents a new approach and methodology for the safety monitoring and early warning of underground railways, demonstrating significant practical significance and application value.
