This study analyses the slope stability of hills under different heights of retaining walls and slope angles, both with and without water pressure, using the Morgenstern-Price analysis method in GeoStudio software. The slip surface option employed is Entry and Exit, and the slope stability material model is Mohr–Coulomb. The deciding parameter for the analysis is the Factor of Safety. The study finds that when water pressure is considered, the stability of slopes with the same angle and wall height is lower than that of slopes without water pressure. Additionally, as the slope angle increases, the stability of the slope decreases. The study also reveals that a slope that is stable at 30˚ under no water pressure condition becomes unstable when water pressure is considered. Finally, based on the available data and analysis results, the study infers that more than half of the area is considered unsafe since slopes with a gradient of more than 30˚ have a factor of safety of less than one. The findings of this study can be used to design and plan effective slope stabilization measures and land use planning in the region.
