esame, considerando inclinazioni del piano di scivolamento pari rispettivamente a 18° e 16° (valori calcolati come media ponderata sulle superfici di scivolamento imposte nelle analisi precedenti) e valori dell’angolo di attrito pari rispettivamente a 25° e 30°. I risultati ottenuti sono rappresentati nella Fig. 3, per la frana 1 (b), per la frana 2 (c) e riassunti in Tab. 5.
