Türkiye Kuvvetli Yer Hareketi Kayıtları Kullanılarak Deprem Kaynaklı Kalıcı Zemin Yer Değiştirmelerinin Tahmin Edilmesi

Newmark kayan blok modeli, deprem kaynaklı zemin yer değiştirmelerinin hesaplanması için sıkça kullanılan bir modeldir. Literatürde bu model kullanılarak çeşitli deprem verilerine göre regresyon analizleri yapılmış ve bazı hesaplama yöntemleri önerilmiştir. Bu çalışmada öncelikle, Türkiye'de 1976 ile 2013 yılları arasında meydana gelmiş önemli depremlerinkayıtları ( Mw >= 5.5) kullanılarak ve önceki çalışmaların Türkiye verilerine göre durumu incelenerek gerekli değerlendirmeler yapılmıştır. Bunu izleyen aşamada da maksimum deprem ivmesine bağlı olarak ortalama ivme (a0)parametresi tanımlanmış ve bu parametreyi içeren yeni bir çözümleme önerilmiştir. Yeni yaklaşımın regresyon uyumu (R2) önceki formlardan daha iyi ve standart sapması daha düşüktür. Bu nedenle, sonuç olarak, önerilen yeni formun kullanılan veriler açısından daha uygun olduğu açık bir şekilde görülmüştür

Estimation of The Amount of Earthquake-Induced Premanent Ground Displacements Using Strong Ground Motion Records in Turkey

Newmark sliding block model is a model frequently used for calculating earthquake-induced ground displacements. Using this model in literature, regression analyses have been carried out according to various earthquake data and some calculation methods have been suggested. In this study, the status of previous studies have been reviewed according to records in Turkey and necessary evaluations have been made using significant earthquake records between 1976 and 2013 in Turkey (Mw >= 5.5). In the next step, average maximum acceleration (a0)parameter has been defined based on maximum earthquake acceleration and a new analysis covering this parameter has been suggested in this study. The regression fit (R2) of the new form is higher and standart deviation of the new approximation is smaller than the previous forms . Therefore, in consequence, it has been clearly seen that the new form is more appropriate for the data used.
