Experimental Investigation of Piles Behaviour Subjected to Lateral Soil Movement In this study, the behaviour of vertical piles installed in order to increase slope stability under lateral soil movement is observed by model tests conducted in a specially built large scale shear box in the geotechnics laboratory of Yıldız Technical University. Laboratory model tests were carried out on sandy soil slopes stabilized with piles. A row of four 800 mm long aluminum pipes with a diameter of 35 mm and wall thickness of 5 mm were used. Pile heads were connected to each other by means of an aluminum beam. The single pile row was subjected to the loading due to lateral soil movement and deformations and bending moments developed in the pile sections were measured by strain gauges attached at different points along the pile lengths. The results obtained from the experiments are compared with the methods found in the literature in order to make a contribution to a better understanding of this complicated geotechnical problem

Bu çalışmada, şevlerin duraylılığını sağlamak amacıyla, şev içerisine yerleştirilen düşey kazıkların yanal zemin hareketi etkisi altında davranışını gözlemlemek için büyük ölçekli bir kesme kutusunda model deneyler yapılmıştır. Gözönüne alınan zemin ortamı kum olup, kazıklı şev duraylılığı problemi modellenmiştir. Deneylerde kazık malzemesi olarak içi boş kesitli alüminyum borular kullanılmıştır. Kazıkların dış çapı 35 mm, et kalınlığı 5 mm ve uzunluğu 800 mm’dir. Yanal yük etkisinde maruz kalan tutulu başlı kazık grubu tek sıra halinde 4 kazıktan oluşmaktadır. Tek sıra kazık grubu yanal olarak yüklenerek meydana gelen kesit tesirleri ve yerdeğiştirmeler kazık kesiti boyunca belirli aralıklarla yerleştirilmiş olan şekil değiştirme ölçerler ve yerdeğiştirme ölçerler yardımı ile belirlenmiştir. Elde edilen sonuçlar kaynaklarda önerilen yöntemler ile karşılaştırılmış ve geoteknik mühendisliğinin bu karmaşık probleminin daha iyi anlaşılması için katkıda bulunulmaya çalışılmıştır
