Analysis of engineering geology between Demirçevre-Sadıkbey (afyonkarahi̇sar)

The need for new settlement areas in earthquake-risk areas requires detailed studies in terms of engineering. A new settlement is planned in the area between Demirçevre -Sadıkbey Province, Afyonkarahisar Province, which is a region which carries risk in terms of seismicity, and the study of this area in terms of engineering geology constitutes the subject of this thesis. Paleozoic aged Afyon Metamorphics form the basis of the study area. Middle-Upper Miocene aged Ömer-Gecek unconformably covers the metamorphics. Quaternary travertine and alluvial deposits are at the top. In order to evaluate the area in terms of engineering geology, 30 drillings with a total depth of 500m, 10 seismic refraction (Jfsis), 5 electrical resistivity (DES) and 5 points microtremor measurements were performed at various points, standard penetration test (SPT) was applied on drill samples. Laboratory tests were carried out in accordance with the relevant standards of the Standards Institute (TSE). The seismicity and risk analysis of the region were made and the study area was evaluated in terms of liquefaction. As a result, with the help of the obtained data, the study area was evaluated in terms of settlement suitability. Keywords: Settlement suitability, Liquefaction, Geotechnics, Earthquake.
