Investigating the effect of oil contamination on soil

Leak of Crude oil from tubes reservoirs and refineries related to the oil industry as well as natural oil eruptions in some areas susceptible and its penetration into the surrounding soil and substructures in addition to destructive environmental impacts such as contamination of groundwater and seawater it causes changes in the geotechnical properties of the soil as well. These changes are a change in physical properties and changes in the soil structure and texture in grain soils and in sticky soils respectively. The problem of stability and resistance of soils contaminated with oil is important for structures oil reservoirs oil pipelines and the stability of slopes. In this research the geotechnical properties of soil impregnated with crude oil with two four and six percent in a period of ten twenty and thirty days have been measured by the results of direct shear tests consolidation and single axial tests for clay soil. The results obtained for this study can be used as an application to prevent the soil damages.
