In this study, the effects of various procedures, Ordinary Method of Slices, Bishop's Modified Method, Spencer's Method, Janbu's Generalized Procedure of Slices and. Wedge Method, on factor of safety for a practical problem taken from Alaybey Shipyard Construction are investigated. Soil profile used in the analyses is a sand fill on a soft clay foundation. General slope stability considerations which are based for stability analyses, the slope stability charts and detailed stability analysis procedures are given in each subsequent section. The computer programs developed for comparing the influences of the methods mentioned above on factor of safety are employed and the charts giving the differences between the factors of safety of various procedures are also developed. Additionally, the effects of these methods on minimum factor of safety are performed. For this purpose, the influences of the shear strengths parameters of the sand fill and the clay foundation on the factor of safety are investigated and the results are also given as the chart. Stability of slopes during earthquakes is given in the last section. A typical soil profile taken from Alaybey Shipyard Construction with the earthquake forces and without considering these forces are analyzed using Wedge Method. For this purpose, a computer program is developed.
