Indian geotechnical journalSummary: During the monsoon season, landslides are common in mountainous areas, disrupting transportation and day-to-day activities. The stability of slopes along rock cuts on mountainous roads is a major problem since it causes traffic disruption, property loss, and even death. Slope stability is a fascinating research area in geology and geotechnical engineering. Aside from the natural strength of the rock mass and its attitude, other unknown factors contribute to slope failure: characteristics, simulation methodologies, failure and applied loads, and so on. The research region is characterized by moderately strong and strongly jointed rocks with harsh terrain features and a history of rockfall events. This geological phenomenon can be found on State Highway-5 Markundi. Based on rock discontinuities and slope face characteristics, the conventional and numerical methods were used to determine the mode of failure of rock cut slopes. The slope failure was investigated using kinematic analysis, and finite element analysis suggests rock slopes will be stable at an angle of 75º. The failure pattern of detached blocks and their potential for additional movement under gravity as well as seismic loading for four locations have been studied using finite element analysis in numerical simulations, and the mean factor of safety (FoS) has been reported as 1.41.
