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