Özet

Purpose: In this study, it is aimed to determine the depths at which liquefaction may occur in earthquake-prone areas and to prepare liquefaction potential maps of these moments. Study design/methodology/approach: In this study, liquefaction potential analysis and mapping of Altınova District of Yalova, which is located on the North Anatolian Fault Line, was carried out. Standard Penetration Tests (SPT) were performed by drilling 6 boreholes in the region. Using the data obtained from the SPT, liquefaction potential analyses were performed using MATLAB software in accordance with the rules specified in Seed-Idriss Simplified Liquefaction Procedure and Turkey Building Earthquake Regulation (TBEC-2018). Then, liquefaction potential maps were produced using ArcGIS program depending on different earthquake magnitudes. Study design/methodology/approach: As a result of this study, liquefaction analyses of the earthquake risky region according to different methods and various earthquake magnitudes were performed, and comprehensive liquefaction potential maps of the region were obtained. Originality/value: In previous studies, liquefaction analyses were performed for certain earthquake magnitudes. In this study, liquefaction analyses were performed for a large number of earthquake magnitudes and the probability of liquefaction at which depth and in which magnitude earthquake was determined and mapped.
