A Comparative Study on Slope Stability Analysis by Different Approaches
Slope stability analysis is of particular significance to geotechnical engineers for construction of railway embankments, canal, road embankments, earth dams, etc. Slope failures can have devastating social and commercial impacts. To assess the safe design of slopes, factor of safety values acts significant roles. Factor of safety values is used to define how close or far slopes are from failure either occurring naturally or induced by manmade activities. Traditional limit-equilibrium method is the most common technique for analysis of slope. In recent times, finite element method (FEM), a powerful, viable alternative technique is available to the geotechnical engineers. In the present investigation, an attempt has been made to study the analysis of slope based on the numerical simulation using Geo-studio software. The parameters of soil strata constituting the slope are determined from laboratory results. The main objective of the present study is to indicate the correlation between factors of safety of embankment using different approaches, e.g., analytical approach and analysis as per “Guidelines for Earthwork in Indian Railway Projects” with finite element modeling. Finally, the paper presents the correlation between the slope angle and factor of safety for cohesive and cohesionless soil.
