Tunnel Monitoring
Understanding Ground Response During Excavation
Tunnel construction involves continuously changing ground conditions as excavation progresses through varying geology and support stages. These changes can lead to deformation, convergence and pore pressure variations that are difficult to interpret consistently across an active excavation.
Instrumentation is typically deployed in phases, with inclinometers, extensometers, piezometers and convergence systems installed as the tunnel advances. The challenge is maintaining consistent interpretation as conditions, geometry and instrumentation evolve.
Sensly provides a structured environment for managing this complexity, enabling consistent interpretation of geotechnical and structural behaviour from early excavation through to completion.
Applying Sensly in Tunnels
Supporting Instrumentation Workflows in Underground Environments
Tunnel instrumentation is continuously adjusted as excavation progresses, with sensors added, relocated or reconfigured in response to changing ground conditions. Maintaining consistency across these changes is critical to ensuring reliable interpretation of behaviour over time.
Sensly supports this by enabling structured sensor configuration and controlled updates as monitoring networks evolve, ensuring data remains consistent across excavation stages. Real-time processing supports trigger-based response conditions, allowing changes in deformation, convergence or pore pressure to be escalated when required.
