EVALUATION OF THE SOIL CHARACTERISTICS AND LIQUEFACTION RISK IN KAZIMPASA, ADAPAZARI (TURKEY), CASE STUDY

Abstract

It is necessary to determine the local soil properties in order to safe constructions in settlement areas under the earthquake hazard. In this study, the local soil conditions of Kazimpasa region in Adapazari were investigated by geological, geophysical and geotechnical data in order to evaluate the soil characteristics and liquefaction risk. 19 seismic and 19 drilling studies results have been evaluated to determine the soil characteristics of the study area. The study area is located in the 1st degree earthquake zone. The geology of the study area is generally controlled by Quaternary aged alluvium and Eocene aged claystones. The local soil classes were determined as Z4 in the alluvium and Z2 in some areas controlled by altered claystones in the study area. The P-wave velocities were measured between 333 - 2026 m/s and the S-wave velocities were measured between 118 - 1089 m/s according to the seismic studies. The ground water level in the alluvium is varying between 0 – 3 m. The liquefaction analysis results indicated that some areas covered with alluvium have liquefaction potential considering the soil properties and seismic activities of the study area.
