Abstract
Many high-rise buildings, transmission towers, and bridges are constructed near slopes and are supported by pile foundations. These structures are exposed to a considerable amount of lateral load due to environmental actions, which is ultimately transferred to the pile foundations.Rapid industrialization means that large quantities of industrial waste are being discharged into surrounding areas, causing contamination of the soil. Soil contamination with oil is a serious worldwide problem.In this research, the thickness of the contaminated layer varied from (0.1 to 0.5) pile length to study the effect of contamination on the behavior of laterally loaded pile. Furthermore, numerical study was performed using 3D PLAXIS FOUNDATION with various percentages of oil content sandy slopes at different densities.The results were showed that reduction of the pile lateral capacity, increasing of the lateral displacement and increasing of maximum bending moment due to an increasing percentage of oil content and thickness of contaminated layer. Furthermore, the behavior of laterally loaded piles embedded in oil contaminated sand slopes changed in a comparison of clean sand slopes.
