ABSTRACT: The slope soil analysis remains a corporate concern in construction
activities. Because of its significance, the evaluation of slope soil stability
has called widespread attention to several researchers all over the world. Many
methods have been technologically advanced to evaluate the stability of slopes
soils founded on distinct expectations and circumstances. Every method has
specific benefits and limits. This work makes a comparison among safety factors and slip surfaces of
slopes soils based on using Limit Equilibrium and Finite Element methods.
Therefore, SLIDE 6.0 and PLAXIS 8.0 software were used for Limit Equilibrium
and Finite Element methods, respectively. The computations of safety factors
were performed for diverse shapes of slopes including different types of soils.
Failure surfaces and values of safety factors obtained were compared for both
methods used. It was noticed that the safety factors obtained from Limit
Equilibrium methods were larger than of which is obtained by the finite element
code. Moreover, an important change is noticed between the slip surfaces obtained by using
both approaches.
