In recent years, due to the increasing use of hydrocarbons by humans, soil contamination has become a concern in environmental and geotechnical engineering fields. In the other words, by the growth and development of
industries, the number of factories, complexes, refineries and oil product
transportation lines around cities increases. Hence, in addition to the environmental concerns caused by the leakage and entrance of pollutions into
groundwater and their side effects, the soil geotechnical characteristics and
bearing capacity of soils contaminated by oil contaminations are subject to
change. Accordingly, in the oil-rich regions of the world, a great deal of
research is devoted to the study of soil refinement, bearing capacity and
instability caused by soil contamination. A numerically study was undertaken to
achieve an accurate and realistic response. As a review of the previous
research indicated, in recent decades, most studies have focused on the
geotechnical properties of contaminated soils and there is only a limited
amount of information about the bearing capacity and the foundation settlement
behavior. Thus the purpose of this paper is to determine the behavior of strip
footings rested on the gasoil and kerosene-contaminated sand slope. After
determining the bearing capacity, the effect of petroleum products, including
gas oil and kerosene oil, on the bearing capacity of strip footings adjacent to
sand slopes was investigated. In this study, variables such as the type and
percentage of contamination, slope angle, footing distance to slope crest and
the thickness of the contaminated layer have been investigated. The results
show that a thicker contaminated layer and a greater degree of contamination
and soil slope will decrease the bearing capacity of the strip footing. Furthermore by increasing the footing distance to slope crest, the bearing capacity of strip foundation is increased. The numerical results have been verified for both the load-settlement diagram and the ultimate bearing capacity of the footing, by recent experimental results.
