The definition of monitoring system for lendslides depends on its specific features, such as the type and direction of movement, geotechnical properties of the soil or rock mass, and type of activity.
Of course, the impact on nearby existing and/or structures within the construction area should also be considered.
The instruments usually used to monitor landslides are:
– Inclinometers: in-depthhorizontal displacements
– Piezometers: groundwater level or pressure
– Ground benchmarks or prisms: displacement of the ground surface
– Clinometers and crackmeters: monitoring of engineering structures in the zone of influence
All instruments can be managed in manual modality, with readings taken at a specific time frequency.
Installing appropriate acquisition units, data transfer tools and software (loggers, GSM modems, total stations,…) allows for an automated real-time landslide monitoring system.
