ESTIMATION OF UNDRAINED SHEAR STRENGTH OF SOIL USING CONE PENETRATION TEST (2013)
This paper shows the determination of undrained shear strength based on cone
resistance from cone penetration test for clayey soil. The test was carried out on ten different suspected clayey soil sites at Ebonyi State College of Education, Ikwo. The cone factor which is the most important for reliable estimation of undrained shear strength from cone penetration was evaluated considering the plasticity index of the soil. The result showed that the cone factor ranges from 11.26 at plasticity index of 12.7 to 16.19 at plasticity index of 30. The result showed an increasing trend. The result also showed quantity of combined clay and silt in the sites. The researcher recommends that the concerned bodies and organizations should insist on the use of the results of soil tests such as the cone penetration test for soil properties determination in the foundation designs of structures to avert structural foundation failures.
