Abstract

The road network in the North of Morocco is often subject to the sliding phenomena leading to slope instabilities which require rapid and expensive interventions. Indeed, significant disorders due to a landslide have occurred at the 34 kilometer point (KP34) on the highway connecting Tangier to Ksar Sghir. In this article, the deformation of a soil stabilized by reinforced concrete piles is studied using finite element modeling. The soil-pile system is modeled using the Elasto-plastic Mohr-Columb Model for the soil and the Elastic model for the pile. Inclinometers were installed on the site to measure soil deformation over time. Results show that the horizontal displacement of the soil is close to that measured in situ. Also, the measured displacements revealed that the method of reinforcement by piles used in some areas of the study is effective in stabilizing landslides, and not for others.
