Earthworks, special foundations and subsurface contracting inevitably involve ground-related deformations that must be monitored. Using geotechnical sensors to carry out this task provides control of geotechnical risks, and can contribute input to the process of optimising the dimensioning of subsurface structures.
Sensors installed during the earthworks project can be retained for long-term monitoring of cuttings and embankments, for example.
Geotechnical sensors are also useful for monitoring soil movement in terms of landslips, settlement, etc. They also contribute to causal diagnostics, deconsolidation risks and identifying any reinforcement work that may be required.
Installed on the surface or below ground, geotechnical sensors can be used to measure:
Sensors for determining soil stress state are called Total Pressure Transducers (TPTs)
Cyclops™ is Sixense’s world leading automated topographic measurement solution in terms of projects completed and result quality, providing :
4DBloc is a GNSS sensor for real-time monitoring of ground or structure deformations.
The 4DBloc system allows :
Synthetic aperture radar
Our 4DSkin solution enables non-contact deformation measurements to be made over large areas of up to several kilometres, at high frequency (typically every 2 minutes) and to a very high level of accuracy (typically 0.2 mm).
3D continuous linear inclinometer
4DShape is an all-in-one solution that uses a flexible chain of 3D inclinometers to monitor the relative movement of vertical, horizontal or converging profiles in soils and on structures.
