Tire soil reinforcement for slope stability improvement in the PK3 + 400 landslide Medea Algeria
Zohra Melaz, Lyazid Guechi, Saad Saghir, Aissa Cheriet
TL;DR
This study explores using recycled tires to stabilize a landslide-prone slope in Medea, Algeria, offering a sustainable and cost-effective solution.
Contribution
The novel use of recycled tire-soil reinforcement for slope stabilization is evaluated as a sustainable solution.
Findings
The slope is stable in dry conditions but becomes unstable when saturated or under seismic loads.
Tire-soil reinforcement increases shear strength and improves safety factors above critical thresholds.
Abstract
Landslides are among the most damaging natural hazards, threatening infrastructure and communities. This study investigates a landslide in Medea, Algeria, located between National Roads 01 and 18, where slope instability disrupts local transport. Geological and geotechnical surveys revealed decompressed marly clays, groundwater infiltration, and seismic activity as the main triggering factors. Stability analyses using Geo-Slope software showed that the slope is stable in dry conditions but becomes unstable when saturated or subjected to seismic loads. To improve safety, a reinforcement technic using recycled tires mixed with soil was evaluated. Numerical simulations confirm that tire–soil reinforcement increases shear strength and raises safety factors above critical thresholds. This sustainable and cost-effective solution demonstrates the potential of recycled materials for slope…
