Étude Géologique et géotechnique de l’effondrement dans les terrains de la commune de Bouraoui Bel Hadef willaya de Jijel.

Abstract

In the southwestern part of the Bouraoui Belhadef district, just next to the youth center on the road to CW 135B, a landslide appears. The landslide that is the subject of our memories appears the construction of limestone marl and schist marl on the embankment loaded by the youth center in the lead. The possible causes of this landslide are the presence of water, the lithology of the soil, the more or less steep slope of the backfill. We used software to study the stability of the slope before and after the geoslope reinforcement is used to calculate certain parameters. The solution proposed to stabilize this land is the sheet pile retaining wall, and the surface water drainage system (drainage ditch) on site, with the safety factor obtained after the embankment reinforcement is satisfactory.
