An experimental study has been carried out to observe the effect of density and moisture on property of cohesive (expansive) soil. At a constant grading of a soil its effect on strength, swelling pressure, permeability and CBR value has been undertaken, as soils are to be used for making road pavement, embankments, dams etc. The stability of an embankment will greatly be influence by the shear parameters which are depend upon the degree of compaction. This paper deals with slope stability evolutions by limit equilibrium (LE) methods and compared with the results from GEOSLOPE software. The LE based methods are compared based on the factor of safety (FOS) obtained from various conditions with simplified slope geometry and shear strength parameters. The slope stability analysis of cohesive soil has been done by SLOPE/W software and is used in under different conditions to evaluate slope stability. Analysis of embankment at different heights of each slope with Bishop Method. In the present study the effect of varying the density and moisture has been studied to determine the properties of cohesive soil namely expansive black cotton soil. It has been concluded that by increasing the dry density, the undrained shear parameters (C & Φ) are improved.
