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. The factors of safety of the slope calculated using these two methods are found to agree closely. Using the earthquake record taken at Bolu station during 12 November, 1999 Düzce earthquake, the dynamic response of the slope i" T.cY0KSlKÖ6RETIMKintDUI Bi-OKOStANlASYON MEMOÖis computed. The computed response is found to simulate the slope failed during the earthquake reasonably well.

Assessment of slope stability in Ankara clay: a case study along E90 highway
Teoman, MB; Topal, Tamer; Isik, NS (2004-05-01)
Some slope instability problems exist in Ankara clay along E90 highway. The purpose of this paper is to determine the mineralogical and geotechnical properties of soils, and to investigate the causes and mechanisms of three rotational landslides along a section of the highway. In order to accomplish these tasks, field studies, laboratory testing, back analyses, and limit equilibrium and finite difference analyses were performed. The landslides are formed within a soil consisting of clay and silt with a litt...
Investigation of the failure mechanism and stabilization of a landslide in weathered tuffite, Giresun, northeastern Turkey
Avsar, Ozgur; Akgün, Haluk; Kockar, Mustafa Kerem (2014-11-01)
This study investigates the causes and failure mechanism of the Aksu landslide that occurred during the construction of the Giresun-Espiye road between KM: 1 + 030-1 + 170 in northern Turkey and recommends proper stabilization techniques. For the purpose of investigating the causes and mechanism of this slope failure, engineering geological mapping, geotechnical investigation and rock mass characterization were performed. From top to bottom, weathered tuffite, tuffite, flysch, and dacitic tuffite were the m...
Assessment of rock slope stability along the proposed Ankara-Pozanti autoroad in Turkey
Avci, Km; Akgün, Haluk; Doyuran, Vedat (1999-01-01)
The main objective of this study is the determination of the slope stability and excavatability category of discontinuous rock exposed between 53 + 000 and 58 + 000 km of the proposed Ankara-Pozanti autoroad in Turkey to provide secure access. The-study area is mostly in the outcrops of highly jointed sandstone with minor layers of marl. This Maastrichtian-Eocene Group also contains conglomerate and limestone bands of flysch character called the Pasadag Group. Quaternary alluvial deposits occur throughout t...
Landslide assessment and stabilization study along the Tarsus - Çamlıyayla provincial road at km: 11+640 -12+080
Ataş, Pelin; Akgün, Haluk; Department of Geological Engineering (2017)
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 ...
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. ...
