Effect of Water on Slope Stability: Comparative Study
Effect of Water on Slope Stability: Comparative Study
ABSTRACT: In response to the increasing phenomena of landslides linked to climate changes
and water management, our study focuses on the stability of slopes under extreme hydraulic conditions.
Using GeoStudio and PETAL-LCPC software for an in-depth comparison, we observed
a notable decrease in the safety coefficient by up to 20% in the presence of water.
The study also reveals significant changes in displacement patterns and stresses within the slopes,
illustrating complex failure modes due to groundwater effects on one hand, and the complexity
of soil-water interactions on the other. These results highlight the importance of considering the
hydraulic and mechanical aspects of soils in the field of civil engineering. Finally, the integration
of multiple calculation methods provides a nuanced analysis of slope stability in our work, essential
for improving landslide prevention and infrastructure safety in response to current climate
challenges and sound design at the Ultimate Limit State (ULS).
