Abstract
Onshore and offshore oil spill contaminate soil. Oil contamination causes several problems not only on environmental concerns for ground water pollution and other possible effects, but also affect on the geotechnical properties of the soil. This thesis presents the results of a series of plain-strain model tests carried out on both clean sand and oil-contaminated sand slopes loaded with a rigid strip footing .The objectives of this study are to determine the influence of oil-contamination on the bearing capacity characteristics and the settlement of the footing resting on sand slopes. Contaminated sand layers were prepared by mixing the sand with an oil content of (0 to 6) % with respect to dry soil to match the field conditions. The investigated parameters include the effect of the distance between the footing and the slope crest (X), slope angle (θ), relative density of sand (Dr), oil content (O.C) and thickness of the contaminated sand layer (LC).The results showed that the bearing capacities decrease and the settlements of the model footings increase with increasing the depth of the contaminated sand layer. Also it was observed that the behavior of the model footings are much dependent on the relative density, slope angle and the location of the footings relative to the slope crest.
