Abstract

P-y eğrilerinin doğru tanımlanması, özellikle sıvılaşma potansiyeli yüksek, sıvılaşabilir suya doygun gevşek kumlu zeminlerde, yatay yüklü kazıkların davranışının doğruluğu için önemlidir. Bu çalışma kapsamında, literatürde genel kabul görmüş yaklaşımlarla, doymuş gevşek kumlu zemine yerleştirilmiş tekil bir kazık için p-y eğrileri hazırlanmış ve bu eğrilere bağlı zemin tepkisinin kazık tasarım parametreleri üzerine etkileri karşılaştırmalı olarak incelenmiştir. Bu çalışmada, bu eğriler kazıkların farklı derinliklerinde API kumu, Reese kumu ve Sıvılaştırılmış kuma göre çizilen eğrilerle temsil edilmiştir. P-y eğrilerindeki bu davranış farkı, yanal yüklü kazıkta oluşan yer değiştirmeleri, eğilme momentlerini, kesme kuvvetlerini ve nihai yanal direnç değerlerini önemli ölçüde etkilemiştir. Kazıkların tasarımında kullanılan önemli çıktılar olan yanal sehimler, eğilme momentleri, kesme kuvveti ve yanal yük taşıma kapasitesi p-y eğrilerindeki farklılıklar dikkate alınarak tasarlanmalıdır.

A Comparative Analytical Investigation on The Effects of Different P-Y Curves for A Laterally Loaded Single Pile Design in Saturated Sandy Soil

Abstract

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.
