Static and Seismic Stability of a Slope Reinforced with Two Rows of Piles

The use of piles for slide stabilization is considered among the most important innovative reinforcement techniques. Piles have been successfully used in many situations to stabilize slopes or as parts a stability improvement. Our case study Tlemcen section. left side roadway collapsed following downstream side. Inclinometer readings showed signs instability with slip depth about 9m near motorway platform. likely causes were removal lower abutment embankment upstream road and establishment an earth deposit which overloaded disrupted flow water downstream. based on installation two rows anti-slip piles. Stability analysis was carried out under static dynamic loads highlights that this solution advantageous effective.
