Abstract
Data collected by monitoring suggest that movement of mudslides essentially develops through alternating stages of undrained-drained deformation. Undrained conditions are established as a consequence of landslide mobilisation or reactivation. Every acceleration phase is followed by progressive deceleration associated with dissipation of excess pore pressure. The paper reports the results of some simple numerical analyses performed in order to investigate the role of pore pressure on the mudslide behaviour.File in questo prodotto:
