Abstract

This study was conducted to evaluate effects by adding oil to clay soil and influences of remained oil in soil as time elapsed. Unconfined compression test and direct shear test were performed to analyze strength properties of contaminants in clayey soil. As a results of $q_u$ test for kerosene and diesel contaminated clayey soil indicate that were decreased from near 5% oil content rapidly and the declination of strength were blunt as oil content over 10%. The cohesions(c) and internal friction angle(${\psi}$) of kerosene contaminated clayey soil were not varied as quantities of kerosene in clayey soil increased. In the case of diesel contaminated clayey soil, the cohesions(c) were decreased and the internal friction angle(${\psi}$) were increased.
