Evaluation of the soil conditions in Alikahya Region (Izmit)

Main Article Content

Talas Fikret Kurnaz


In this study, the soil conditions of Alikahya region (Izmit) were investigated by the results of geological, geophysical and geotechnical survey results. Alikahya region is almost entirely located on sub-mid-upper Eocene aged rocks and Quaternary aged sediments. The alluvium thickness is nearly 300 m. According to seismic studies, P-wave velocities are between 277-2562 m/sec, and S-wave velocities are between 110-1427 m/sec in the study area. The determined local soil classes are Z-3 on the clay stones and Z-4 on the Quaternary aged alluvium, respectively. The ground water level varies between 1-2 m depths in the alluvium. Alikahya region located on first degree earthquake risk zone and liquefaction analysis results indicated that the existence of local liquefiable areas in the study area.
