Slope stability assessment is an important aspect of geotechnical engineering for ensuring the safety of natural and engineered slopes. The present study evaluates the stability of a natural hill slope located at Swaminarayan Hills, Narhe, Pune, Maharashtra, using both manual and numerical analysis techniques. Three representative soil samples were collected from different locations on the slope and subjected to laboratory investigations including moisture content determination, density measurement, Atterberg limits, and Triaxial Compression Tests. The results showed that the moisture content of the soil samples varied from 15.49% to 22.77%, while the dry density ranged from 1.19 g/cc to 1.41 g/cc. The Atterberg limit tests indicated liquid limit values between 44% and 45% and plasticity index values ranging from 14% to 19.44%. Shear strength parameters obtained from triaxial testing and Mohr–Coulomb failure analysis revealed cohesion values of 80–90 kPa and angles of internal friction ranging from 22.53° to 25°. These geotechnical parameters were utilized for slope stability evaluation through the Infinite Slope Method and GeoStudio SLOPE/W software. A numerical slope model was developed using field-measured geometry and laboratory-derived soil properties to assess the stability of the selected hill slope. The results obtained from manual calculations and software-based analysis were compared to evaluate the applicability and reliability of both methods. The study demonstrates that the integration of laboratory testing, analytical calculations, and numerical modelling provides a comprehensive approach for slope stability assessment. The findings can be useful for the planning, design, and management of slopes in similar hilly terrains subjected to environmental and geotechnical influences.
KEYWORDS
The stability of the selected hill slope was assessed using the Infinite Slope Method and GeoStudio SLOPE/W. The obtained factor of safety values ranged from 7.10–7.44 for manual analysis and 5.11–5.47 for GeoStudio analysis. The minimum factor of safety obtained was 5.11, which is significantly higher than the recommended minimum value of 1.5. Therefore, the selected hill slope is considered stable under the existing conditions. The study also showed that GeoStudio provides a more realistic assessment of slope stability compared to manual calculations.
