Stability analysis of soil-nailed slopes using the Spencer Method

This study analyzes the stability of a 12-meter-high slope reinforced with soil nails, using the Spencer limit equilibrium method. The evaluation of safety factors was performed under various loading conditions, including self-weight, road surcharge, water table presence, and seismic activity. The results show that soil nailing significantly improves slope stability, with the safety factor increasing from 0,48 to 1,48 under self-weight loading. Numerical simulation software was used for the modeling and calculations, yielding accurate results that are highly suitable for designing retaining structures. This research demonstrates the effectiveness of soil nailing as a reinforcement method, highlighting its ability to enhance stability in slopes subjected to different types of loading. The study also emphasizes the importance of considering multiple factors, such as hydraulic pressures and seismic effects, when designing slope stabilization systems. The reliable outcomes obtained from numerical analysis reinforce the role of advanced simulation tools in ensuring slope safety, particularly in areas prone to environmental or man-made stressors.
