Comparative Analysis of Bishop, Sarma and Janbu Slope Stability Methods Applied to Large Rock Slopes: A Case Study

ABSTRACT: Slope stability analysis is of paramount importance in geotechnical engineering, as slope failure can result in significant risks to the safety of infrastructure and nearby communities. Several methods have been developed to evaluate the stability of slopes, including Sarma, Bishop and Jambu methods, each with its particularities and variations. The three methods mentioned are based on limit equilibrium theories and differ from each other due to the considerations made, which imply small differences in results depending on the application conditions. Therefore, this study aimed to compare these three methods in a soft rock mass slope scenario and analyze the divergences in results that may arise between them. The study sought to identify whether these divergences could present significant risks and determine which method is most appropriate for stability analysis in this specific context, concluding with the definition of recommendations for geotechnical engineering professionals in their slope stability analyzes in similar contexts, always seeking to ensure safety and efficiency in decision-making in civil engineering projects.
