Özet:

The correct definition of p-y curves is important for the accuracy of the behavior of horizontally loaded piles, especially in liquefiable water-saturated loose sandy soils with high liquefaction potential. Within the scope of this study, p-y curves of a single pile placed in a saturated loose sandy soil were prepared with the approaches generally accepted in the literature, and the effects of the soil response depending on these curves on the pile design parameters were examined comparatively. In this study, these curves drawn according to API sand, Reese sand and Liquefied sand at different depths of the pile. This behavior difference in the p-y curves significantly affected the displacements, bending moments, shear forces and ultimate lateral resistance values that occur in the lateral loaded pile. Lateral deflections, bending moments, shear force and lateral load carrying capacity of the pile, which are important outputs used in the design of the piles, should be designed with considering the differences in the p-y curves.
