Assessment and Stabilization of Natural Landslide Hazards by a Reinforcement System

The phenomenon of landslides is a constant global natural hazard that occurs in most countries of the world. Algeria, particularly the northern region, is a case in point. In this respect, the present study examines the phenomenon of landslides in the Setif region, in order to protect and preserve the multilayer soil that supports the reinforced structures. Numerical modeling predicts the risk of sliding pillars against the wall. This study establishes an analytical calculation with a reference model. The investigations are carried out as a comparative study by three programs. The solution proposed is to reinforce the soil with an adequate system. The present study suggests that the use of different software within reasonable ranges has considerable effects on the total ground motion. Finally, it is concluded that the use of numerical analysis procedures could be more time and cost-effective in the design of geotechnical projects.
