Study on Index and Engineering Properties of Soils Found in Konso Town

  Pampana Vasudeva Rao,  Democracy Dilla

The geotechnical engineers repeatedly facing problems for identification and classification of the various grades of tropically weathered residual soils in Ethiopia. An experimental study was performed to evaluate the geotechnical properties of weathered residual laterite soils of south western Ethiopia (konso town). Residual tropical soils are sensitive to handling and disturbance. Plasticity chart is good reference to evaluate the properties of tropical residual soils. It is observed from the experimental results that increasing trend in natural moisture content, free swell index, specific gravity and density with increase in depths, whereas decreasing trend was observed in liquid limit and plastic limit. Clay fraction varies between 40.7 to 58.6%, the unconfined compression strength test results are ranges between 245 to 332 kN/ m2, the cohesion and angle of internal friction values are varies between 160.76 to 191.34 kN/m2 and 10 to 12º
