INVESTIGATION OF LIQUEFACTION POTENTIAL UTILIZING NONLINEAR SEISMIC SITE RESPONSE OF THE PROJECT AREA LOCATED IN YALOVA PROVINCE SÜLEYMANBEY DISTRICT

The occurrence of significant liquefaction-induced damage in structures due to earthquakes has increased the importance of liquefaction analyses over time and has enabled computer-aided analyses to be used more frequently. This study evaluated the liquefaction potential for the project area located in the Süleymanbey District of Yalova Province considering the seismic field response. Seismic field response analyses were carried out in the Deepsoil software using real earthquake scenarios. Peak ground acceleration values were obtained by utilizing the nonlinear analysis method using Çanakkale Ayvacık, Afyonkarahisar Çobanlar, Aegean Sea İzmir Seferihisar, Düzce (Bolu) and Kocaeli Earthquake data with Mw=5.3, 5.8, 6.6, 7.1 and 7.6 magnitudes, respectively. Using the data obtained from earthquake scenarios in the relevant project area as an input enabled the analyses to be carried out realistically. Liquefaction analyses were performed for each earthquake magnitude utilizing the nine different methods in the Novoliq software and simplified theoretical method; then, the results were compared. While the liquefaction potential in the project area for earthquakes with a magnitude of Mw=5.3, 5.8, and 6.6 varies, liquefaction risk was observed throughout the area in earthquakes with a magnitude of Mw=7.1 and Mw=7.6.
