  • Abstract:
  • The stability of slopes is always under severe threats in many parts of Western Ghats, especially in Attapadi during rainy season, causing disruption and loss of human life and economy. Slope instability is a common phenomenon with a high level of risk in living hoods. It is dangerous because the soil strata’s shear strength is weakened by the slope-forming materials gradual migration. To minimize the instability of the soil slope, a critical evaluation of the slope section is required. The stability of the slope is measured by its factor of safety using geometric and shear strength parameters based on infinite slopes. The region of Attapadi in Kerala has been selected as the study area for the geotechnical investigations. Undisturbed soil samples were collected from seven different landslide’s vulnerable locations were tested for their geotechnical properties. A detailed numerical analysis was carried out for the slope failure area. The slope stability depends on the soil shear strength parameters such as cohesion, angle of internal friction, unit weight of soil and slope geometry. From the soil sample analysis, the slope failure phenomena and factor of safety have been calculated using Rocscience software, which is a finite element software and suggests suitable remedial measures. The knowledge of slope behavior and productive measures in the study area is improved by this investigation.
