Abstract

The shear strength of soil is the resistance to deformation by continuous shear displacement of soil particles. The angle of internal friction and cohesion are the shear strength parameters of soil. The effect of fines on peak friction angle and critical friction angle is studied. The sand and silt samples are collected and five samples are prepared with various mix ratios of medium sand and silt. Its index properties such as specific gravity, particle size distribution, maximum dry density and optimum moisture content are determined. Using direct shear test the shear strength parameters are found for every sample. The peak friction angle, critical friction angle and maximum shear stress for each sample are compared and studied. It is found that the shear strength parameter values decreases with the decrease in the particle size of the soil and also it appears that D10 has higher influence on peak friction angle and critical friction angle.
