During the foundation excavation of an industrial plant in Eskişehir, Turkey, a landslide occurred in the neighbouring slope, and consequently, the excavation had to be stopped. The instability occurred in a natural slope which had an average slope angle of 9-13 degrees. The aerial extent of the slide mass was 400 m by 115 m. The material in the slope was 7 to 20 meter-thick colluvium (slide debris), which constitutes a historic landslide mass, underlain by a gravelly sandy silty clay matrix containing limestone blocks, weathered tuff and tuff. Soil profile and location of the slip surface were determined through a site investigation program including nine boreholes and inclinometers. A back analysis was carried out and shear strength parameters of the slope forming materials were determined. Slope stability analyses were carried out, stabilization alternatives were evaluated and slope stabilization by piled retaining walls was considered as the most feasible alternative. The analyses and design procedure for the piles will be presented together with a summary of existing analyses and design methods for landslide stabilizing piles.

Housing after disaster: A post occupancy evaluation of a reconstruction project
Dikmen, Nese; Elias Özkan, Soofia Tahira (Elsevier BV, 2016-10)
The permanent post-disaster houses constructed in the rural areas of Cankiri Province in Turkey, were investigated as part of a post-occupancy evaluation of the reconstruction project, undertaken by the Turkish Ministry of Environment and Urbanisation. The aim of the study was to examine whether houses constructed with Typical or Custom Designs met the needs of the users in the region or not. Field surveys were undertaken, and face to face interviews were conducted with the beneficiaries of the reconstructi...
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. ...
Slope stability analysis of a borax stockpile site
Karpuz, Celal (2009-01-01)
Stability investigations were conducted for a slope at the back of a borax stockpile site near the Bandirma Harbor in the northwestern Turkey. There was a slope failure at the site causing damage in the concrete sections of the harbour in front. Investigations started with deformation monitoring with an inclinometer. Failure mechanisms were determined with back analysis using method of slices and finite difference models. A combined failure mechanism involving a circular failure surface in the slope and a n...
Seismic performance evaluation of traditional timber HA plus /-mA plus /-AY frames: capacity spectrum method based assessment
Aktas, Yasemin Didem; Türer, Ahmet (2016-11-01)
Timber constructions have been widely suggested to be seismically resistant based on post-disaster reconnaissance studies. This observation has, however, remained to a large extent anecdotal due to the lack of experimental work supporting it, especially for certain timber architectural forms, including traditional timber frame "hA+/-mA+/-AY" structures. To fill this gap, the authors carried out an extensive full-scale testing scheme using frames of various geometrical configurations, tested under reverse-cy...
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 ...
