Abstract:
The structural integrity of highway embankments, engineered cut slopes, and natural hillsides is an essential concern for geotechnical professionals and civil engineers worldwide. Failures along transport corridors frequently lead to catastrophic ground movements, extensive infrastructure damage, economic paralysis, and significant risk to human life(Aktas et al., 2025). Over several decades, numerous analytical and computational procedures have been formulated to quantify slope equilibrium. These computational techniques differ substantially in their underlying theoretical assumptions spanning classic limit equilibrium formulations, progressive failure mechanisms, and finite element deformation analyses as well as in their implementation via design charts or numerical simulation packages (Ikeagwuani & Nwonu, 2023). Despite these operational differences, all methods evaluate safety margins by establishing a global Factor of Safety 
or by comparing mobilized driving stresses directly against the available shear strength envelope of the soil mass. In highway construction, various stabilization and slope reinforcement techniques are deployed, each distinguished by installation complexity, long-term durability, and overall project cost (Xu & Zhang, 2025). The primary aim of this paper is to investigate slope stability across artificial transportation embankments and natural formations, placing special emphasis on extreme hydrological conditions and parameter sensitivity within limit equilibrium models (Utepov et al., 2022). This analytical exploration aims to refine predictive capabilities, optimize geotechnical design practices, and guide the deployment of resilient engineering countermeasures along modern transport networks (Sharma & Shrivastava, 2025).
