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 kaymadairesi, güvenlik sayısı ve kayma potansiyeli incelenmiştir. Güvenlik sayısının 0,80 mertebelerine düşmesihalinde 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 içselkuvvetler ve yer değiştirme değerleri göz önüne alındığında 8,00 m uzunluğunda bitişik nizam tek sıra 60,00cm’lik fore kazık seçilmiştir. Böylece, yolun güvenli biçimde servise açılabilmesi amacı ile kazıklı duvar önlemialınarak 4,90 seviyesine yükseltilen güvenlik sayısı ve yaklaşık 65,00 mm’lik kazık tepe deplasmanı ile şevinstabilite problemi çözülmüştür.

In this study, the stability problem of the landslideoccurred at 0.65th km of road that has a 20.00 m width and 4 lanes, which islocated at Ciftlikkoy district of Yalova province, was investigated with twodifferent finite element software. Physical and mechanical properties obtainedfrom the in-situ samples were used during the modelling processes. The circleof failure, factor of safety and failure possibilities of slope were observedin the case of external static and dynamic load conditions within the stabilityanalysis performed by Slide program. In the event that the factor of safetyvalue reached the level around 0.80, the current failure behavior was occurred.Besides, axial force, shear force, bending moment and deformation values ofpiles were calculated by Plaxis. An adjacent bored pile application formed asingle row has a 60.00 cm in diameter and 8.00 m in length was chosen with respectto the internal force and displacement results of 6.00, 8.00, 10.00, 12.00 and14.00 m pile lengths as well as constant diameter. Therefore, the stabilityproblem of slope was solved by the precaution of piled wall In this study, the stability problem of the landslideoccurred at 0.65th km of road that has a 20.00 m width and 4 lanes, which islocated at Ciftlikkoy district of Yalova province, was investigated with twodifferent finite element software.
