        abstract = {The shear parameters of soil are required for determining the bearing capacity of soils for all types of foundation. The equipment required for the determination of shear parameters at the accurate drainage conditions are costly and hence in most of the projects shear parameters are determined from the Standard penetration test. The correlations between the index properties of soil and its engineering properties are immensely useful since it is easier to determine index properties and is relatively difficult to determine the engineering properties. It is easy to determine the particle size distribution since the equipment required is cheap and easily available. Twenty granular soil samples of varying gradation parameters like uniformity coefficient and coefficient of curvature were prepared by mixing gravel and sand in various proportions. The shear parameters are determined from large scale direct shear test carried out in a shear box of size 300 mm x 300 mm x 200 mm. Thus, correlations are developed between angle of shearing resistance and gradation parameters like coefficient of curvature and uniformity coefficient. It is observed from the results that angle of shearing resistance is inversely proportional to the uniformity coefficient.},
