No full textNatural and man-induced stress evolution of slopes: the Monte Mario hill in Rome
No full textThe paper deals with stress-release effects induced by man-made cuts or excavations into natural stiff clay slopes that experienced erosion in response to valley deepening. The study was focused on the Monte Mario hill in Rome (Italy), which formed part of an area of recent urban expansion. The methodology of the study relied on a reference engineering-geology model, which was developed on the basis of site and laboratory data and stress-strain analyses. The latter analyses were carried out with the finite-difference code FLAC 4.0. Numerical modelling was based on a sequential approach, taking into account the main evolutionary stages of the Tiber river valley in Rome's urban area and then making cuts at the bottom of the slope located south of the Monte Mario Astronomical Observatory. The simulation revealed the stress-release effects that fluvial erosion and excavation fronts have caused on the investigated slopes and their consequent gravitational instabilities. These processes appear with metre-scale displacements, followed by stress-release cracks (actually observed on the slopes under review). In quantifying stress-release deformations, the simulation took into account the possible role of creep in the observed retardation of stress-release effects

Rainfall as triggering factor of slope movements in Southern Italy: Montalbano Ionico case record
No full textThe aim of this paper is to define the role of rainfall on landslides in Southern Italy by using hydrological/statistical approach. Among the villages affected by slope movements, Montalbano Ionico has been selected as example of shallow landslides. Its most recent landslide evolution is characterized by low intensity phenomena that can be classified as retrogressive and widening composite rapid earth slide - earth fall. Their high frequency and the caused damage imply a high risk degree. This study confirms how complex and how very diverse are the phenomena that govern the effects of rainfall upon slope stability. Nevertheless, geomorphological analyses focus on the importance of some previous instability marks to predict the future slope evolution by landslides; when these marks exist, the weight of unusually heavy cumulative rainfall on the successive landslide collapse is resulted 30% - 40%
