Stability Analysis of Soil Slopes Using Limilt Analysis

The limit equilibrium method is commonly used for slope stability analysis.Limit equilibrium method however is not rigorous because neither static nor kinematical admissibility conditions are satisfied.Limit analysis takes advantage of the lower-and upper-bound theorems of plasticity theory to provide bounds on the true solution of a stability.The theoretical basis and procedure for slope limit analysis is presented.Example of slope is selected from the literature and analyzed using both limit equilibrium and limit analysis.Factors of safety from limit equilibrium and limit analysis are compared.
