Today, the environment is affected by different pollution, which pollution with oil and oil derivatives such as gasoline and diesel is one of the most dangerous. Organic chemicals are the foundation of numerous industries such as fuel refining, petrochemical complexes, pesticides and detergents. the Improper use of organic chemicals can cause irreparable damage to the environment, which has caused growing concern in many countries, in addition to the destructive effects of the environment, such as groundwater and seawater pollution ،it can changes the geotechnical properties of the soil, which are founded in cohesive soils by changing the texture and overall structure of the soil. This experimental investigation by Atterberg limits, unconfined compressive strength and direct shear tests was performed to assess the effect gasoline contamination on the geotechnical properties of silty soils which was polluted by different amounts of diesel (5, 10 ,15%). Comparison of the results showed 27% decrease in Liquid limits and 48% decrease in plastic limits with increasing oil contamination. This decreasing trend was observed in the shear strength parameters of soil contaminated with different percentages of diesel ،there is also a direct correlation between the amount of reduction and the increase in soil dry density.
