Analysis of Slope Stability and Landslide by using PLAXIS 2D

Analysis of slopes for stability and safety is a measure area of concern in civil engineering. This is the reasons that do many analysis techniques have been developed so far. Traditional ways of slopes stability analysis involved determination of factor of safety for a slope to take safety precautions against any instability. Various researchers worked to develop a new method in which probability of failure or reliability of slope is calculated. Thus, basically to different approaches of slope stability analysis are available with us deterministic approach and probabilistic (or reliability) approach. In this paper past trends in slope stability analysis are discussed with evaluation of each method. A brief review of available methods has also been presented here along with the advantages and limitations of their use. Slope stability analysis can be performed using deterministic or probabilistic input parameter the finite element program PLAXIS 2D was used for evaluating the stability of natural slope. Plaxis2D can model heterogeneous soil type, complex stratigraphic and slip surface geometry, and variable pore water pressure condition using a large selection of soil models.
