The rapid expansion of urban subway systems has increased the demand for shield tunneling methods capable of navigating densely populated areas and sensitive risk zones. However, these projects often encounter challenges such as uneven ground settlement and risks to nearby structures. To address these issues, a novel intelligent management and control platform has been developed, combining analytical models with advanced digital tools to enhance safety and precision in tunneling operations.
This platform leverages technologies like BIM, GIS, IoT, and 3D geoscience modeling to create a digital twin environment for construction sites. By integrating real-time data and theoretical models, it predicts immediate and long-term settlement impacts with high accuracy. The system also enables proactive risk management by issuing alerts based on calculated and observed data discrepancies. This allows construction teams to adjust shield machine parameters and implement mitigation measures, reducing potential hazards.
A notable application of this platform occurred during the Beijing Metro Line 12 project, where it ensured the safe under-crossing of Line 10 by dynamically monitoring and controlling settlement risks. Beyond improving project safety, the platform demonstrates significant cost-saving potential through its ability to streamline operations and reduce error margins. As urban tunneling becomes increasingly complex, this intelligent platform offers a sustainable and efficient solution for future infrastructure development.
