Abstract
Kabylia is mountainous and coastline region of Algeria. Every year, particularly in the winter, it is affected by landslides displacing an important volume of detritic materials, and causing damages to infrastructures, housing and public facilities. It takes place in geological formations that are particularly favourable to this type of movement, because of the heterogeneity of their facies and the impermeability of some layers. Experience shows that the main cause of the landslides in this region is the combination of several passive and active factors, as geology, morphology, hydrology, climate and anthropic activities. The exceptional rains of winter 2012 triggered a series of landslides in this region, among which the landslide occurred at PK 226+300 of the National Road RN 24, at a place named Assoumeth-Boulimat, Béjaia department, is one of the most spectacular. The landslide caused the collapse of a section of the road of about 120 meters, with a main scarp of about 8 meters. During the firstly time of the field observation, 18 hours, the landslide mass and the road moved 10 meters. This paper describes this landslide triggered by rainfall and unfavourable geological, hydrogeological and geotechnical conditions. The geotechnical study and methodology of stabilization in two phases will be presented and discussed. Stability calculations were conducted to understand the triggering of the landslide.

Case Study of Landslides in Kabylia Region, Algeria
Chicago, Illinois
Kabylia is mountainous and coastline region of Algeria. Every year, particularly in the winter, it is affected by landslides displacing an important volume of detritic materials, and causing damages to infrastructures, housing and public facilities. It takes place in geological formations that are particularly favourable to this type of movement, because of the heterogeneity of their facies and the impermeability of some layers. Experience shows that the main cause of the landslides in this region is the combination of several passive and active factors, as geology, morphology, hydrology, climate and anthropic activities. The exceptional rains of winter 2012 triggered a series of landslides in this region, among which the landslide occurred at PK 226+300 of the National Road RN 24, at a place named Assoumeth-Boulimat, Béjaia department, is one of the most spectacular. The landslide caused the collapse of a section of the road of about 120 meters, with a main scarp of about 8 meters. During the firstly time of the field observation, 18 hours, the landslide mass and the road moved 10 meters. This paper describes this landslide triggered by rainfall and unfavourable geological, hydrogeological and geotechnical conditions. The geotechnical study and methodology of stabilization in two phases will be presented and discussed. Stability calculations were conducted to understand the triggering of the landslide.
