Application of the 2D and 3D FEM-SSR Methods in Slope Stability Investigations: A Case Study from Bor？ka (Artvin) Region

In the scope of this study, the stability problem in the soil slope excavated for the construction of the new government hospital in the Yeniyol (Bor？ka-Artvin) quarter was investigated in terms of engineering geology. The studies were performed in three stages as field, laboratory works and stability analyses. For this purpose, three boreholes with a total of 108 meters in length were drilled, geophysical studies were performed along the one line and inclinometer measurements were taken in one borehole. The talus consisting of two levels as sandy-gravelly and silty-clayey soils overlies the Eocene-aged Kabak？y Formation comprising the volcanic rocks. To determine the physico-mechanical properties of talus, undisturbed samples were taken from boreholes. 2D and 3D FEM-SSR stability analyses were evaluated using the obtained data from field and laboratory studies. It was determined that the stability analyses results are compatible with each other. As a result, it was determined that unforeseen engineering problems will be encountered if measures are not taken in the slope. It is suggested to apply fore pile application as support method
