Supervision monitoring and maintenance

Slopes must be monitored when the occurrence of limit states cannot be proven sufficiently unlikely by calculation or prescriptive measures, or when the assumptions made in calculations are not based on reliable data.

Monitoring should provide ground-water levels or pore-water pressures for effective stress analysis, lateral and vertical ground movements, the depth and shape of any existing slide for remedial work, and rates of movement. For embankments, Eurocode 7 Part 1 lists additional situations needing monitoring and specifies the contents of a suitable monitoring programme.
