ABSTRACT
This paper generally deals with the slope stability analysis of soil and an easy way to stabilize
the slope to achieve high shear strength. Correlations between Factor of Safety (FS) and soil parameters
i.e. cohesion, friction and unit weight are developed in this paper. Correlations among factor of safeties
in natural, stepped and nailed form are also developed using linear regression analysis. Soil is not
a homogeneous material and its properties are changing in different conditions and in different places.
In case of slopes, there are many ways to stabilize it by nailing or stepping techniques. In this paper,
both these methods are investigated in detail and compared to each other to know that which method
gives better result. The graphs which shows the percent improvement of safety value are provided in
the result section. This paper is providing a summary of the slopes safety issues having different soil
properties. A software namely Slide is used for Limit Equilibrium (LE) analysis of the pre-defined soil
slope model. For correlations, MS Excel and SPSS software are used. The correlations equations are
provided in the results section.
