Abstract
In this study, the stability problem of the landslide occurred at 0.65th km of road that has a 20.00 m width and 4 lanes, which is located at Ciftlikkoy district of Yalova province, was investigated with two different finite element software. Physical and mechanical properties obtained from the in-situ samples were used during the modelling processes. The circle of failure, factor of safety and failure possibilities of slope were observed in the case of external static and dynamic load conditions within the stability analysis performed by Slide program. In the event that the factor of safety value reached the level around 0.80, the current failure behavior was occurred. Besides, axial force, shear force, bending moment and deformation values of piles were calculated by Plaxis. An adjacent bored pile application formed a single row has a 60.00 cm in diameter and 8.00 m in length was chosen with respect to the internal force and displacement results of 6.00, 8.00, 10.00, 12.00 and 14.00 m pile lengths as well as constant diameter.

Özet
Bu çalışmada, Yalova ili Çiftlikköy ilçesi gençlik caddesindeki 4 şeritli 20,00 m genişliğindeki yolun 0,65. km’sinde meydana gelen heyelanın stabilite problemi iki farklı sonlu elemanlar programında incelenmiştir. Modellemeler sırasında arazideki doğal numunelerden elde edilen fiziksel ve mekanik özellikler kullanılmıştır. Slide programı ile gerçekleştirilen stabilite analizlerinde statik ve dinamik yük etkimesi durumunda şevin kayma dairesi, güvenlik sayısı ve kayma potansiyeli incelenmiştir. Güvenlik sayısının 0,80 mertebelerine düşmesi halinde mevcut göçme davranışı meydana gelmiştir. Ayrıca Plaxis programında kazıklara gelen eksenel kuvvet, kesme kuvveti, eğilme momenti ve yer değiştirme değerleri hesaplanmıştır. Çap sabit tutularak 6,00; 8,00; 10,00; 12,00 ve 14,00 m uzunluğunda kazık uygulaması ile gerçekleştirilen çözüm önerilerine göre kazıklardaki içsel kuvvetler ve yer değiştirme değerleri göz önüne alındığında 8,00 m uzunluğunda bitişik nizam tek sıra 60,00 cm’lik fore kazık seçilmiştir. Böylece, yolun güvenli biçimde servise açılabilmesi amacı ile kazıklı duvar önlemi alınarak 4,90 seviyesine yükseltilen güvenlik sayısı ve yaklaşık 65,00 mm’lik kazık tepe deplasmanı ile şevin stabilite problemi çözülmüştür.
