Abstract
Deep foundations, including piles, are employed in types of coastal soil because the soil in such regions may be subjected to several variables that alter the engineering features of the soil, like oil contamination. Together with the loads caused by supported superstructures, the pile foundations may also be susceptible to torsional loads from eccentric, horizontal loads brought on by winds, earthquakes, ship accidents, and waves. Tests have been conducted in this laboratory investigation to examine the behavior of piles under torsional load (T) in polluted sandy soil. Also, tests investigated how the Lp/Dp ratio affected the piles' bearing capacity. Details are supplied, including the impact of the relative density of the piles (Dr) and the thickness of the contaminated layer (Lc) on the piles' maximum torsional bearing capacity. According to the findings, in loose sand at (Lc/Lp) =1, the torsional moment at 1° for piles subjected to pure torsion torque in contaminated sand is found to be (25, 31, and 39%) of the maximum torsional torque for Lp/Dp = (20, 16.67, and 13.3), respectively, while this ratio is found to be (33, 43, and 52%) for dense sand (Dr = 80%). It also indicated that the torsional torque of piles installed in loose sand (Dr = 30%) for Lp/Dp = (20, 16.67, and 13.3) is less than the torsional torque in dense sand (Dr = 80%) by (13, 12, and 11%), respectively. These results show that the pile design must take into account the considerable reduction in torsional load when the pile is installed in contaminated sand.
