ABSTRACT
In the field of land management, the limit equilibrium calculation method is a mathematical
method that harmonizes the complex interplay of diverse factors determining the slope stability.
Rooted in mechanical and mathematical principles, this method has paramount significance for
guiding the course of safe land management in mountainous regions, especially in the case of
infrastructure development projects. Conventional limit equilibrium techniques, while provid-
ing preliminary stability assessments, often neglect key factors that can trigger slope failure.
These approaches traditionally ignore the spatial variations in soil properties, the temporal dy-
namics of phenomena, the kinetic responses to external loads, the complexities of geological
formations, and the influences of the hydrological and climatic conditions on slope stability. Our
innovative method adopts an enriched mathematical framework that redefines the landscape
of force equilibrium techniques. We meticulously tailor this framework by adapting the founda-
tional relationships derived from the Mohr-Coulomb shear strength criterion to accommodate
the spatially variable geomechanical parameters. This adaptation allows us to capture the nu-
anced shifts in mechanical properties over the extent of the slope. Furthermore, we introduce
supplementary equations that seamlessly integrate the influences of traffic-induced loads and
hydraulic pressures, while also statistically quantifying the contributions of stabilizing struc-
tures. To determine the efficacy of this geomatic and landscape-centric numerical tool, we have
subjected it to rigorous testing on a test slope. The outcomes derived from our mathematical
model reveal the primacy of traffic-related forces as the main destabilizing agents, contrasted
with the strengthening effects of reinforcements in maintaining slope stability.
