Performance of Axially Loaded Pile Group in Oil Contaminated Kanhan Sand
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 6
Abstract
The ground is being contaminated by petrochemical activities, oil spills, and pipeline or reservoir leakage everyday. This contamination has been proven to alter the geotechnical properties of soil, and researchers have extensively studied the properties of contaminated granular soils. But the effect of oil contamination on the geotechnical properties of sandy soils has not yet been well evaluated. Hence, a comprehensive set of laboratory pile load tests has been conducted in contaminated sand. This paper presents an experimental investigation aimed for understanding the performance of pile group in oil-contaminated sand. The model parameter are varied, namely thickness of contaminated layer and percentage of oil contamination. The tests were performed with an oil content of 0, 0.5, 1.0, 1.5, 2.0, 2.5 and 3.0 % with respect to dry soil to match the field condition. This is an extensive program of work, done on single pile in oil content of 0 to 3.0 % which was published earlier. From the results, it is observed that the maximum pile capacity in all percentages of oil contamination was found in the range of LC/LP = 0.50 to 1.0. Pile Capacity Ratio (PCR) is affected remarkably by the thickness of the contaminated-sand layer with respect to the length of pile. PCR is also affected by percentage of oil contamination.
