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.
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. Therefore, the stability
problem of slope was solved by the precaution of piled wall In this study, the stability problem of the landslide

factor of safety and 65.00 mm top displacement of pile.
