Tunnels

OSMOS can be used to monitor the structural behaviour of tunnels in real time and to measure the impact of the environment:

Tunnels are particularly subject to stress - ground movement, soil decompression during the excavation phase, water infiltration, overload of the structure above the tunnel… Monitoring of these structures is essential to detect signs of instability and prevent the impact of the environment on the availability of the tunnel.

All of the information is continuously accessible, in real time. This provides managers with the facts they need to answer essential questions, such as:​

  • Is the structure’s integrity compatible with its operating conditions?
  • How can I optimize the structure’s operations?
  • Are visible problems evolving over time?
  • Can scheduled maintenance be postponed?
  • Has the structure been damaged by a disaster (fire, earthquake, etc.)?
  • How did the structure behave during extraordinary stress?
  • How is the structure changing over time?

Final and reassuring reports and analysis:

  • Detecting the compression constraints resulting from poor distribution of the weight itself or a spot overload
  • Detecting the effects of differential settlements, which may be the result of localized collapses of galleries, or the presence of hard geological points
  • Monitoring excavation work
