Abstract

Crude oil products and its derivatives have contaminated soil for a long time. crude oil contamination is an unavoidable consequence of rapid over population and industrialization process. Crude oil contamination can change soil geotechnical behavior and, affects soil strength, foundation bearing capacity and, slope stability. On the other hand, “mini-cone’ tests have rapidly become the most famous type of on-site testing. Because, the mini cone is a fast and, economical experiment that continuously provides information on the geological layout and, the proper assessment of soil properties. This paper compares mini cone data and, sandy-clay soils behavior changes with the physical modelling method and, based on changing clay amount, crude oil and, moisture contents with a focus on calculating the value of Ic. Results showed that the tip and, the side resistances of the “mini-cone” was decreased in mixed soils with increasing crude oil content and, changing in moisture contents. It is important that the changes of the resistance parameters are directly proportional to the soils compaction in the laboratory chamber. Also, with these changes and, Ic calculation found that the soils behavior shifted towards finer-grained soils. In this way, the soils gradually changes their behavior from sand to silt and, then to clay.
