| Zusammenfassung |
| Rainfall-induced shallow landslides, also called "soil slips", are becoming
ever more frequent all over the world and are receiving a rising interest in
consequence of the heavy damage they produce. At the University of Parma, a
simplified physically based model has been recently set up for the evaluation
of the safety factor of slopes which are potentially at risk of a soil slip.
This model, based on the limit equilibrium method applied to an infinite
slope, takes into account some simplified hypotheses on the water down-flow
and defines a direct correlation between the safety factor of the slope and
the rainfall depth. In this paper, this model is explained in detail and is
used in a back analysis process to verify its capability to foresee the
triggering instant of rainfall-induced shallow landslides for some recent
case studies in the Emilia Romagna Apennines (Northern Italy). The results of
the analyses and of the model implementation are finally shown. |
