Abstract

Balikesir province Ayvalık district (Balıkesir, Turkey), the study area, is located on the southern branch of the North Anatolian Fault Zone where some earthquake, 1867 Edremit (M=7.0), 1919 Ayvalik-Sarmisakli (Mw= 7.2), 1944 Edremit (Mw=6.4) and 1953 Yenice (Mw= 7.2) earthquakes, occurred in the historical and the instrumental period. The groundwater depth is very low on the coast of Altınova neighborhood of Ayvalık district and sandy soil are widespread. In this study, liquefaction potential and liquefaction severity maps of the coastal part of Altınova district (Ayvalık, Balıkesir) were produced. The safety factor of the soil layers against liquefaction was calculated with the simplified procedure using the SPT-N value. In this study, spatial distributions of safety factor against liquefaction, liquefaction probabilities and corrected SPT-N values of soil layers at 4, 8, 12 and 16 m were found. According to the liquefaction potential map, it is seen that 11.8% of the study area will not liquefy. 64.1% of the study area has "low", 20.5% "medium" and 3.6% "high" liquefaction potential. Of the 4723 buildings in the study area, 584 are in areas where there will be no liquefaction, 3034 are in areas with low liquefaction potential, 909 are in areas with medium liquefaction potential and 196 are in areas with high liquefaction potential. According to the liquefaction intensity map produced in this study, it is seen that in the event of a scenario earthquake, there will be no liquefaction in 1.3% of the study area, liquefaction will develop with “very low intensity” in 33.3%, liquefaction will develop with “low intensity” in 65% and “moderate intensity” in 0.3%.

Özet

Balıkesir ili Ayvalık ilçesi (Balıkesir, Türkiye) çalışma alanı, Kuzey Anadolu Fay Zonu'nun güney kolu üzerinde yer almakta olup, tarihsel ve aletsel dönemde 1867 Edremit (M=7,0), 1919 Ayvalık-Sarmısaklı (Mw=7,2), 1944 Edremit (Mw=6,4) ve 1953 Yenice (Mw=7,2) depremleri meydana gelmiştir. Ayvalık ilçesi Altınova mahallesi sahilinde yeraltı suyu derinliği çok az olup kumlu zeminler yayılım göstermektedir. Bu çalışmada Altınova mahallesi sahil kısmının (Ayvalık, Balıkesir) sıvılaşma potansiyeli ve sıvılaşma şiddeti haritaları üretilmiştir. Zemim tabakalarının sıvılaşmaya karşı güvenlik sayısı SPT-N değeri kullanan basitleştirilmiş prosedürle hesaplanmıştır. Bu çalışmada zemin tabakalarının sıvılaşmaya karşı güvenlik sayısının, sıvılaşma olasılıklarının ve düzeltilmiş SPT-N değerlerinin 4, 8, 12 ve 16 m’deki mekânsal dağılımları bulunmuştur. Sıvılaşma potansiyeli haritasına göre inceleme alanının % 11,8’inde sıvılaşma olmayacağı görülmektedir. İnceleme alanının %64,1’i “düşük”, %20,5’i “orta”, %3,6’sı “yüksek” sıvılaşma potansiyeline sahiptir. İnceleme alanında yer alan 4723 binadan 584’ü sıvılaşma olmayacak alanda, 3034’ü düşük sıvılaşma potansiyelli alanda, 909’u orta sıvılaşma potansiyelli alanda ve 196’sı yüksek sıvılaşma potansiyelli alanda bulunmaktadır. Bu çalışmada üretilen sıvılaşma şiddeti haritasına göre senaryo depremin gerçekleşmesi durumunda inceleme alanının %1,3’ünde sıvılaşma olmayacağı, %33,3’ünde sıvılaşmanın “çok düşük şiddetli”, %65’inde sıvılaşmanın “düşük şiddetli” ve %0,3’ünde “orta şiddetli” gelişeceği görülmektedir.
