Abstract
Eğim şevlerinde gözlenen yenilme
mekanizmaların geleneksel kinematik analiz yöntemleri ile değerlendirilmesi
mümkün olmamakta, bu nedenle, söz konusu yenilme mekanizmalarının gelişmiş şev
duraylılığı analiz yöntemleri ile değerlendirilmesi gerekmektedir. Bu çalışma
kapsamında, tamamen ve kısmi süreksizlik kontrollü çift düzlemsel yenilme
mekanizmasının limit denge, sonlu elemanlar ve ayrık elemanlar yöntemleri
kullanılarak incelenmesi ve sonuçların karşılaştırılması amaçlanmıştır. Şev ile
aynı eğime sahip kireçtaşı tabakalar içeren bir eğim şevinde şev duraylılığı
analizleri gerçekleştirilmiştir. Gerçekleştirilen analiz sonuçlarına göre, çift
düzlemsel yenilme mekanizması analizlerinde limit denge esaslı yöntem sonlu
elemanlar ve ayrık elemanlar esaslı yöntemlere kıyasla daha tutucu sonuçlar
vermektedir.
