Stability analysis by the end element method of Zonguldak Kılıç

Landslides are a complex natural phenomenon and, for many countries, have inherent risks. Landslides formed by long-term, heavy rainfall or earthquake triggering affect many people's vital activities and damage their infrastructures in terms of their location. Zonguldak is located in the risky area of the Western Black Sea, and when the general topography is examined, the mountains rise steeply in an east-west direction. In this study, ground parameters related to Kozlu Kılıç region, which is a risk area of landslide, were obtained from detailed ground and geotechnical reports. With this geotechnical data, numerical model was created; the static state behavior is analyzed by modeling with the program based on the finite element of the landslide region. According to the analysis results, the largest displacement is for the first length section; was determined as the middle part of the landslide area for the second length section in the crown of the landslide area. The heel part of the landslide area is located in the safe part for both length sections. It has been found that when the structure loads are analyzed in the model, they increase the horizontal and vertical displacement values. At the same time, it is seen from the results of the first aspect analysis that the seasonal variability of the underground water level is more sensitive to the disposal of the loose material. When the results of this study are evaluated; the improvement of the loose and weak material on the surface of the ground by a suitable method or the horizontal support systems in the crown area to provide excavation safety and to construct the structure is proposed in this study.
