During the road extension works of the Tarsus - Çamlıyayla Provincial Road at KM: 11+640 -12+080, a landslide occurred due to the construction of a steeper slope at the road side for wall construction. The purpose of this thesis is to determine the critical failure location of the landslide and to determine the necessary slope stabilization methods in order to prevent the development of a larger potential landslide that may occur in the future. For this purpose, necessary engineering geological in-situ and laboratory studies have been performed. After establishing the landslide model by the help of the geotechnical information collected, back analysis has been performed at three cross sections along the landslide in order to determine the shear strength parameters of the landslide material. Afterwards, the states of static and pseudo static condition of the landslide have been analyzed by using limit equilibrium method. As a result of these studies, the most suitable stabilization method has been performed by applying a rock buttress at the toe of the landslide, followed by unloading the landslide material in collaboration with surface and subsurface drainage along the landslide area. vi In addition to these studies, deformation analysis of the landslide has been modeled under static condition by the finite element method (FEM) before and after the remediation. It was concluded that the deformation analyses results obtained from the FEM were in a good agreement with the results of the inclinometer measurements along the landslide area. The remediation study has been based and assessed considering these deformation results. It was observed that the safety factor results obtained from FEM and limit equilibrium analysis were close under static conditions.

Stability analysis of a coupled structure: a railway tunnel and a road cut slope Ünlütürk, Burcu; Bilgin, Hasan Aydın; Department of Mining Engineering (2018) A road-cut slope is planned for the construction of a new highway at Zonguldak province. This slope will be excavated by bench blasting method in close proximity to the No 50 Turkish State Railway Tunnel which is a masonry lined 84 years old tunnel in service. The excavation will continue until –approximately- 56 m horizontal and 55 m vertical distances remain to the tunnel lining. The plane failure risk of the slope and the damage risk of the tunnel are two major risks. Investigating stability of the slope...
Stability analyses of a highway embankment slope failed during Düzce earthquake Keklikoğlu, Ebru; Bakır, Sadık; Department of Civil Engineering (2002) In this study, the slope failure of Bakacak during 1999 Düzce earthquake at Bolu Mountain Crossing on Ankara - Istanbul state highway is studied. First, soil parameters at the time of failure are investigated based on laboratory tests and back analyses. Then, these parameters are used to calculate the factor of safety of the slope employing two different methods, namely, limit equilibrium and c-<J) reduction in stress-deformation analyses. Finite difference method is utilized in stress-deformation analyses....
Landslide stabilization in weathered tuffite, northern Turkey Avşar, Özgür; Akgün, Haluk; Department of Geological Engineering (2004) A landslide occurred during the construction of the Giresun ا Espiye road between Km: 1+030 ا 1+170 in April 2003. Investigating the causes and mechanism of this slope failure along with suggesting a proper stabilization technique is aimed in this study. For that purpose, a detailed site investigation study, including engineering geological mapping, drilling work, in situ and laboratory tests, was performed. Weathered tuffite, tuffite, flysch and dacitic tuffite, from top to bottom, are the major units in t...
Stability assessment of the landslide in Bartın Kirazlı bridge dam diversion km: 18 + 325 – 18 + 421 segment Görbil, Barış; Akgün, Haluk; Koçkar, Mustafa Kerem; Department of Geological Engineering (2019) Bartın Kirazlı Bridge Dam construction has started on Gökırmak stream in 1999 for the purposes of irrigation and power generation and is continuing at present. By the end of construction, Gökırmak stream level will reach +105 meters, and the existing Bartın – Safranbolu (D755) Highway will be submerged under water. A new alignment is determined for the relocation of the submerged road and named as the "Kirazlı Bridge Dam Diversion". With the start of the new highway construction, the paleo – landslide regio...
Slope stability assessment of a re-activated landslide on the Artvin-Savsat junction of a provincial road in Meydancik, Turkey Topsakal, Ebru; Topal, Tamer (Springer Science and Business Media LLC, 2015-03-01) The purpose of this study is to determine the most suitable remediation techniques for an active landslide area in Turkey, using a geological engineering assessment of a re-activated landslide that occurred during the construction of the Artvin-Savsat Junction on the Meydancik Provincial Road, at Km: 12 + 200. For this, the geotechnical parameters of the mobilized geological material-which is colluvium along the sliding surface-were determined by back analyses of the landslide at three geological sections. ...
