Short summary
Slope failure is extremely common in mountainous areas. Therefore, the stability and potential failure of slopes must be analysed accurately. For most fractured rock slopes, the aforementioned analyses are considerably challenging. This study aims to propose a comprehensive approach that combines three well-established methods to conduct the aformentioned analyses. Finally, the critical slip surface, factor of safety, and accumulation distance are selected for safety assurance in slope analysis.
