    Stability analysis of stone column slopes under different earthquake loads
    (Bursa Uludağ Üniversitesi, 2022-08-07) Vekli, Mustafa; Çadır, Cenk Cuma
    How a slope behaves under the action of a dynamic load such as an earthquake is of great importance in stability analyses of slopes. Improving the region where slope failure occurs or preventing potential slope failure can lead to reducing the factors that excite movement in a slope and/or increasing the sliding resistance of the soils. In this study, the stone column method was used as an improvement technique. In the analysis performed with Plaxis 2D, safety factors were defined for slopes with different slope angles, soil cohesion, and three different earthquake magnitudes. Later, the slopes with the same characteristics were improved using the stone column method. The slopes were improved with different s/D ratios and different internal friction angles of the stone column. The same earthquake forces were also applied to the improved slopes and the factors of safety were determined. In the study, slope models with stone columns designed without the effect of earthquake force showed an increase in safety values in the range of 1.01to 1.34 times compared to slope models without stone columns. It was found that the safety values of the slope models with stone columns increased by 1.02- 1.80 times compared to the slope models without stone columns under the effect of earthquake force.
