In this study, the design of safe slopes was investigated, which is one of the main topics in geotechnical engineering. Another factor that should be considered in the design of safe slopes is seismic loads in addition to static loads. As part of the study, a series of slope stability analyzes were performed using finite element software by applying earthquakes with different characteristics to the model slope, which was designed with the intention of investigating slope behavior under seismic loads. The model slope designed in this context was analyzed with 12 real earthquake record data that occurred in different regions with different scenarios and had many station measurements. As a result, the effects of these earthquakes on the stability of the designed model slope were pointed out and the points that should be considered to obtain safer and more economical results in slope design in the direction of the obtained data.

MODEL BİR ŞEV İLE DEPREM ÖZELLİKLERİNİN ŞEV STABİLİTESİNE ETKİLERİNİN İNCELENMESİ

Öz

Bu çalışmada, geoteknik mühendisliğinin başlıca konuları arasında yer alan güvenli şevlerin tasarımı konusu incelenmiştir. Güvenli şevlerin tasarımı için dikkat edilmesi gereken statik yükler kadar önemli bir diğer etken ise, sismik yüklerdir. Sismik yükler altında şev davranışının irdelenmesi niyetiyle tasarlanmış olan model şeve farklı özellikteki depremler etki ettirilerek sonlu eleman yazılımı ile bir dizi şev stabilite analizleri yapılmıştır. Bu kapsamda tasarlanan model şev, farklı özelliklerdeki senaryolar ile çeşitli bölgelerde meydana gelmiş, çok sayıda istasyon ölçümleri bulunan 12 adet gerçek deprem kayıt verisi ile analiz edilmiştir. Sonuç olarak, bu depremlerin tasarlanmış olan model şevin stabilitesine olan etkileri ortaya koyulmuş ve elde edilen veriler doğrultusunda şev tasarımında daha güvenli ve daha ekonomik sonuçlar alınması için dikkat edilmesi gereken hususlara değinilmiştir.
