Cover Story: Abutment stability analysis is one of the most critical and challenging parts of an arch dam design due to the related complex geotechnical conditions and the high uncertainties regarding geometry and material properties. The drastic consequences of dam failures bring about the need for advanced and reliable methodologies for evaluating the safety of the abutments’ rock wedges. However, among the developed methods, the traditional Limit Equilibrium Method (LEM) is frequently utilized due to its simplicity and practicality. This study provides a discussion of the application and limitations of LEM in a safety assessment of dam-foundation systems. By comparing the LEM with advanced numerical methodologies, the presented research contributes to informed decision-making in the safety and stability analysis of complex geotechnical structures.
