What is it about?
This study focuses on the evaluation of slope stability, which is crucial in geotechnical engineering to prevent slope failures that can cause significant loss of life and property. While traditional and modern methods exist for slope stability analysis, the study highlights the increasing importance of computer-based approaches in recent years. The research investigates the effectiveness of advanced machine learning (ML) algorithms for classification-based slope stability assessment. It examines the impact of various input parameters, such as slope height, slope angle, unit volume weight, internal friction angle of the soil, cohesion of the slope material, and water pressure ratio, on slope stability potential. To simplify application development and enable rapid and comprehensive comparisons of ML algorithms, the study employs automated machine learning (AutoML) approaches. It compares ensemble, boosting, bagging, and traditional ML algorithms. The weighted ensemble learning algorithm provided by the AutoGluon package outperformed other algorithms, achieving an impressive testing and training accuracy rate of 97.5%. The study concludes that unit volume weight and internal friction angle of the soil are the most important factors in classifying slope stability. Overall, the research significantly advances slope stability assessment, achieving one of the highest accuracies among various classification-based studies.
