Abstract
Soil contamination with oil has become a major problem, due to the significant effect of crude oil on the geotechnical properties of the surrounding soil, so it is crucial to study the geotechnical properties of the oil-contaminated soil. Many researchers have been interested in studying the effect of oil contamination on the mechanical properties of soil. However, the dynamic behavior of oil-contaminated soils has been studied by few or almost rare researches. This thesis first studied the shear properties of oil-contaminated sand and sand containing 3% silt to determine the effect of oil contamination on both forms of soil. Finally, two-dimensional finite element modeling was used for dynamic numerical analysis of oil-contaminated sand. Results indicated that adding oil to sand may cause a decrease in shear resistance. The results also showed that exposed earthquakes on oil-contaminated sand caused an increase in the settlement of building constructed in the soil with increasing oil concentration in the sand. The vertical and horizontal strain of the contaminated sand increases with increasing oil contamination in the sand.
