Seismic Monitoring of Metro Tunnel
Quick Facts
- Add facts in ACF “Quick Facts”.
Challenge
Monitor the structural response of the metro tunnel during demolition and new construction works in a seismically active urban zone, while ensuring uninterrupted metro operations.
Solution
The system consists of:
- Nine (9) acceleration channels for real-time monitoring of tunnel structural response.
- Automatic visualization of recorded seismic events on a dedicated web interface.
- Automatic reporting of events in PDF format for engineering documentation and analysis.
Outcomes
The deployment provided metro authorities and contractors with reliable, real-time insights into the tunnel’s structural performance. The system enabled early detection of abnormal vibrations during demolition and construction activities, ensured compliance with safety regulations, and delivered an archived dataset of seismic responses for engineering validation. This case demonstrated the value of seismic monitoring of a metro tunnel in safeguarding underground transportation infrastructure in highly dynamic construction environments.
