Geosentetik Donatılı İstinat Duvarının Analitik, Deneysel ve Sonlu Elemanlar Yöntemleri ile Performans Analizi

Abstract

İnşa edilmelerinin kolaylığı ve deprem yükleri altında sergiledikleri performanstan dolayı donatılı zemin uygulaması ile inşa edilen istinat duvarlarına olan ilgi dünya çapında artmaktadır. Bu çalışmada 450 mm yüksekliğinde kum ve kil dolguya sahip donatılı istinat duvarları inşa edilerek köprü ayağı yükleme şartlarında test edilmiştir. Elde edilen test sonuçlarından yararlanılarak sonlu elemanlar modeli oluşturulmuştur. Sonlu elemanlar ile yapılan parametrik çalışmada donatı rijitliği, donatı sıklığı ve donatı uzunluğunun temel oturmasına, istinat duvarı boyunca oluşan yatay deplasmanlara, her bir donatı üzerinde oluşan maksimum çekme kuvveti ile toplam maksimum çekme kuvvetine ve şev duyarlılığı üzerindeki etkileri araştırılmıştır.

Performance Analysis of Geosynthetic Reinforced Earth Wall by Analytical Experimental and Finite Element Methods

Abstract

Ease of construction and performance under earthquake loads causes interest in construction of reinforced earth walls worldwide. In this study, reinforced earth walls with sand and clay backfill at a height of 450 mm are constructed and tested under bridge abutment loading conditions. A finite element analysis is performed and results are compared with experiment results. In the parametric study made by conducting finite element method, effect of reinforcement stiffness and reinforcement density on the horizontal displacements along the retaining wall face, the maximum tensile force, total maximum tensile force, and slope stability are investigated.
