Analysis of Slope Stability in Construction

This paper aims to systematically analyze multiple critical factors influencing slope stability, particularly the interrelationship among pore pressure, evolution of material properties, and the factor of safety (FOS). By establishing a finite element model, an in-depth investigation into slope sliding behavior was conducted, leading to the following conclusions: (1) When the factor of safety (FOS) reaches 1.9, the slope exhibits non-convergence, indicating the onset of instability, which highlights the necessity of particular attention to stability during the design process under critical conditions; (2) The non-uniform distribution of pore pressure and the presence of unsaturated soil layers significantly impact slope stability. This is particularly critical in the toe region, where sliding phenomena are notably severe and warrant close scrutiny; (3) The study reveals a nonlinear relationship between maximum slope displacement and FOS, especially as values approach the limit, characterized by a sharp decline in stability. The findings provide crucial data support and theoretical guidance for slope design, reinforcement measures, groundwater management strategies, and the develop
