Abstract
Climate action is one of the main causes of sliding of natural and artificial slopes. The climate change that knows the Northern Algeria in recent years (precipitation rate often exceeds the seasonal average observed during the 1990s) contributed significantly to the revival and the intense activity of several very large landslides. The Ain El Hammam landslide is one of the most active cases knows in the region of Tizi-Ouzou. It is an old movement, reactivated by heavy rainfall in 2005, which affects the town of Ain El Hammam and the downstream side thereof. The unstable area is spread over an area greater than 23 hectares and has implemented three deformation mechanisms. This communication is devoted to the study and numerical modeling of progressive failure of the Ain El Hammam slope under the effect of the climate variability and the fluctuations of the water table in this site. The results show the significant effect of the water factor on the development, activity and the failure growth of this landslide as well as the evolution of the safety factor as a function of these parameters. Moreover, the results represent adequately the morphology and activity of the movement observed on the site.
