The slope stability issue in Albania is of great importance, because of the
terrain configuration engineers cannot avoid the construction in difficult
sites and unfortunately there are many cases where slides have occurred. As
it is known, due to the complexity of the problem, many theories and analysis
methods are developed, each one of them having their own simplifications and
assumptions. When analysing a slope stability one has to take in consideration
the fact that, like the vast majority of geotechnical engineering topics, the
problem is characterized by many uncertainties which are mainly related to
the geotechnical parameters (angle of friction, cohesion, weight density etc.)
of the slope material, the potential slip surface (position and geometry),
the slope geometry itself, the seismic force etc. That is why a probabilistic
approach, to take account for these uncertainties and site variations, is
needed in order to have more reliable results. The probabilistic approach of
the problem can be achieved using what is called a reliability analysis, from
which can be obtained the reliability index (β) and the probability of failure
(pf). The purpose of this paper is to give a brief example on how the reliability
analysis can be implemented in the slope stability analysis for the potential
plane failure surface (simplified Culmann Method) and therefore to highlight
its importance. This is achieved by using two common methods; Duncan
Method as a simplified version of FOSM and Point Estimate Method (PEM).
