Abstract:
Despite Advancements In Recognition, Prediction, And Preventive Measures, Landslides Continue To Cause Significant Social, Economic, And Environmental Damage In The Nilgiris District, Tamil Nadu. This Persistent Issue Stems From The Complexity Of Slope Failure Mechanisms And Our Incomplete Understanding Of The Underlying Factors. In This Study, Four Soil Samples Were Collected From Frequently Affected Landslide Sites In The Nilgiris District And Subjected To Geotechnical Analysis, Including Tests For Cohesion, Angle Of Friction, And Atterberg’s Limits. These Soil Properties Were Then Used As Input Parameters For Slope Stability Analysis Conducted Using Oasys Slope. Additionally, Scanning Electron Microscope (SEM) Imaging And Energy Dispersive X-Ray Analyzer (EDX) Testing Were Performed To Further Characterize The Soil Composition. The Landslide Site’s Satellite Imagery Was Obtained From Google Earth And Converted Into Data Points. Using TCX Converter And Quick Grid, The Slope Profile Was Plotted For Analysis. Rainfall Data From Nearby Rain Gauge Stations Were Also Collected And Incorporated Into The Study. Based On These Inputs, The Factor Of Safety Was Determined, And Site-specific Remedial Measures Were Proposed. The Findings From This Study Can Guide The Design And Implementation Of Appropriate Retaining Structures To Enhance Slope Stability And Mitigate Future Landslides.
