Comparative Analysis of Slope Stability Using Simplified Fellenius and Bishop Methods: Influence of Geotechnical Parameters on Factor of Safety

Abstract

The present article investigates the stability of slopes, which is essential for preventing natural disasters such as landslides that affect infrastructure and human lives. Highlighting the relevance of landslides in Brazil and globally, the study emphasizes the need for efficient methods to analyze and predict these events. Using the Fellenius and Simplified Bishop methods, the research calculates the factor of safety for slopes in the Barbosa area, Colombia, considering specific geotechnical parameters, including cohesion, friction angle, and soil unit weight. With the aid of Slide2 software, the analyses detail how variations in these parameters influence slope stability. The results show that a deep understanding of these parameters is crucial for predicting and mitigating landslides. It is concluded that both methods are effective in assessing slope stability, highlighting the importance of understanding how different conditions affect the factor of safety. The analyses provide valuable information for geotechnical engineering, enabling the implementation of preventive measures in risk areas. In addition to contributing to technical knowledge, the research offers a foundation for developing precise and effective strategies to ensure infrastructure safety, mitigating the impacts of natural disasters. The insights provided can guide engineers and specialists in adopting safer practices and developing action plans for landslide prevention, benefiting society and the environment.
