Abstract

canakkale is a settlement located in the northwest of Turkey with relatively low strength soils under high seismic hazard. The depth of the bedrock was calculated based on microtremor measurements as the resonance frequency was variable, and a correlation was obtained by performing regression analysis based on the exponential variation trend curve. At the same time, resonance frequency values obtained from canakkale soils were recalculated as variables with 30 depth-resonance frequency correlations obtained before. The variation of the regression coefficients with the depths of the basin was examined. Especially, it has been observed that a-coefficient can be grouped with four different depths based on value ranges.
