Comparative Safety Analyses of Slope-Shallow Foundation Interaction under Static and Dynamic Loading Conditions

Öz

This study is focused on the safety analysis of the shallow foundations located on cohesive homogenous slopes that has different shear strength characteristics. Static and dynamic analyses have been conducted with a well-known commercial finite element logic-based two dimensional numerical software. Dynamic analyses are performed with regard to the consideration of the Samos-İzmir earth-quake that happened in 30 October 2020. The change of the slope geometry depending on the differentiation of the slope height and inclination is also considered. The interaction between the slope-shallow foundation is investigated regarding different relative distances of the foundation from the slope edge and considering various loading magnitudes for the foundation. The results of the analyses are evaluated in terms of the factor of safety values to interpret the degree of the effects of foreseen variants on the integrated system stability.

Statik ve Dinamik Yükleme Koşulları Altında Şev-Yüzeysel Temel Etkileşiminin Karşılaştırmalı Güvenlik Analizi

Öz

Bu çalışma, farklı kayma dayanımı özelliklerine sahip kohezyonlu homojen şevler üzerinde yer alan yüzeysel temellerin güvenlik analizine odaklanmıştır. İyi bilinen bir ticari sonlu elemanlar mantığı tabanlı iki boyutlu sayısal bir yazılım kullanılarak statik ve dinamik analizler gerçekleştirmiştir. 30 Ekim 2020'de meydana gelen Samos-İzmir depremi dikkate alınarak dinamik analizler uygulanmıştır. Şev yüksekliği ve eğiminin farklılaşmasına bağlı olarak şev geometrisinin değişimi de dikkate alınmıştır. Şev-yüzeysel temel etkileşimi, temelin şev kenarından farklı göreli mesafeleri ve temel için çeşitli yükleme büyüklükleri dikkate alınarak incelenmiştir. Analiz sonuçları, öngörülen değişkenlerin bütünsel sistem stabilitesi üzerindeki etkilerinin derecesini yorumlamak için güvenlik faktörü değerleri açısından yorumlanmıştır.
