Learning objectives
Il corso fornisce gli elementi necessari al riconoscimento dei meccanismi di instabilità dei versanti naturali e dei fronti di scavo, alla parametrizzazione dei materiali e dei processi ed all'analisi delle condizioni di stabilità.
Vengono fornite indicazioni sui metodi di mitigazione della pericolosità e sui metodi ed interventi di stabilizzazione
