One of the most important problems in civil engineering, especially in urban areas, is slope stability analysis. The type of soil material is very important in slope stability analysis. If slopes are made from soils with desirable resistance properties, then the stability increases. In this article, the aim is to study the effect of single weak layer on safety factor of a slope stability in static and quasi-static situations also unreinforced slopes and reinforced slopes using nails. Also, the effects of the depth and thickness of the weak layer are considered. Results are obtained from GEOSLOPE software, which shows reduction in safety factor and also when single weak layer and the depth and thickness increases, safety factor decreases.
