In this study, the effect of slope and soil parameters on the slope stability has been investigated. The slope heights, the angle of slope, the weight per unit of volume, the angle of internal friction and the cohesion have been used as the slope and the soil parameters. The parameter levels have been selected according to these values and the critic safety factors have been determined with 1280 analyses. In analyses, Slide computer program has been employed and the critic safety factors have been obtained according to Bishop Method. By using these safety factors, the average Signal/Noise (S/N) ratios have been calculated with regard to Taguchi Method for each parameters and the parameter levels. And then statistical analyses have been performed for the selected different mathematical models by using the average S/N ratios. End of study, the best model, which will be used practically in determining of the critic safety factor, has been improved. Consequently, the safety factors calculated with this model have been compared with the safety factors obtained according to the Bishop Method in the computer program for the same parameter levels. It has been observed that the safety factors calculated with the model and the safety factors obtained according to the Bishop Method are close to each other.
