Koyulhisar settlement area is located on the northern flank of Kelkit valley which is seismically active and landslide-prone area. The settlement area was adversely affected from active landslides and some of the houses were evacuated. The purpose of this thesis is to delineate areas where slope instability exists within the Koyulhisar settlement area, and to investigate an active landslide by means of field observations, drilling, sampling, field and laboratory testing, and in-situ monitoring using inclinometer. Based on the field studies, it is observed that flyschoidal sequence as bedrock and colluvium consisting clay and silt with some gravel are the main lithological units exposed in the study area. Two landslide affected areas are identified, the one investigated due to its adverse effect to some important governmental buildings, has a non-circular failure surface due to the existence of the flyschoidal sequence below the colluvium. The inclinometer measurements reveal that the displacements are local and their velocities are generally less than 14 mm/year indicating that the landslide is an extremely slow landslide. In addition, high groundwater table is observed as one of the major parameters in occurrence of landslide.

Assessment of slope stability and monitoring of a landslide in the Koyulhisar settlement area (Sivas, Turkey)
Topal, Tamer (2015-09-01)
The Koyulhisar settlement area is located in the seismically active zone of Kelkit valley. The settlement area has been adversely affected by active landslides as a result of which some of the houses have been evacuated. In this study, areas within the Koyulhisar settlement area where the landslides exist were delineated with a field mapping technique, and active landslides were investigated by means of field observations, drilling, sampling, field and laboratory testing, and in situ monitoring using an inc...
Sedimentological and cyclostratigraphic analysis of upper part of the kartal formation (sw of Ankara)
Aghayev, Rufat; Yılmaz, İsmail Ömer; Department of Geological Engineering (2008)
The Montian Kartal Formation lies in the south-west of Ankara region and overlies the Upper Cretaceous Beyobasi Formation and is overlain by Thanetian Kırkkavak Formation conformably in the studied region (Kayabası village, NW of town of Haymana). A 283 m stratigraphic section, which is mainly composed of an alternation siliciclastic and carbonate rocks has been measured in the Kartal Formation within the Haymana-Polatlı basin. The aim of this study is to carry out the sedimentological and cyclostratigraphi...
Structural Evaluation and Strengthening of Zeynelbey Tomb in Hasankeyf, Turkey
Türer, Ahmet (2010-10-08)
Hasankeyf historic settlement area is one the most important sites in southeastern Anatolia which dates back to the 15(th) century. Zeynelbey Tomb is a distinct cylindrical structure has a height of 9.6 m and with double domes extending to an overall height of 16.5m; however, the outer dome suffers from multiple and large vertical tension cracks threatening the overall structural stability and safety of the structure. A preliminary visual inspection and structural evaluation using analytical modeling was ca...
Investigation of rock slope stability for an abandoned limestone quarry in Konya Turkey
Kalpakçı, Volkan; Öztürk, Şevki; Topal, Tamer; Huvaj Sarıhan, Nejan (2016-06-12)
Slope stability problems were encountered in an abandoned quarry which is planned to be used as recreational area by the municipality of Selcuklu in Konya, Turkey. The rock in the quarry is primarily composed of micritic limestone which contains karstic cavities mainly controlled by joints. In order to assess the stability of the abandoned quarry, discontinuity survey, laboratory tests, kinematic and rock slope stability analyses were performed. Based on the analyses, planar and wedge failures as well as ro...
Investigation of Byzantine Mortars from a Basilica in Side Archaeological Site
Güney, Bilge Alp (null; 2017-02-01)
Side Archaeological Site is located in Antalya Province, Turkey. Although there are varying references about the foundation of the city, the city was most prosperous in the 2nd and 3rd century AD, during Roman period. The Byzantine Basilica in the city is dated back to 5th century AD. For the conservation works of the basilica, mortar samples were collected from different parts of the building and investigated for their basic physical, physico-mechanical and compositional properties. For the determination o...
