İngilizce Özet: 

The evaluation of potential rock slope failures using stereographic projection techniques known as kinematic
analysis is one of the most important parts of a slope stability investigation to be carried out in in jointed rock
media.., In conventional stereoprojection techniques for the assessment of possible rock slope failures,, the peak
orientations of joints together with the slope geometry and the friction angle of the weakness planes are used,,
Other possiMe joint orientations which may be encountered in the rock media are ignored.. In the presemi study,
possible wedge failures which can develop in jointed andésites cropped out .Ankara, and its vicinity were investigated
using both conventional and probabilistic kinematic analysis methods, and risk maps were produced using
the results obtained from kinematic analysis and. a. comparison was made between the results: According to the
results obtained front this study, probabilistic risk map are more realistic than the map using conventional kinematic
analysis,, because, all the actual wedge type slope failures developed in the study area are located on the
risk zones of the probabilistic risk map. When three peak orientations of the discontinuities are used for the preparation
of the risk map, 20% of the study shows wedge type failure risk. However, 'this value goes up to 73%
when the probabilistic kinematic analysis: is applied, in conclusion, each possible discontinuity orientation must
be taken into consideration in a kinematic analysis research program.. This phenomenon is important for the selection
and planning of settlement regions particularly, because,, a failure can cause important hazards ami loss
of life.. Besides, the procedure described in the present study is very simple.
