In recent years, Reinforced Earth retaining structures have become more desirable for construction and civil engineering projects because of their suitable performance, variation of design and construction methods. In this article, the performance of back-to-back reinforced earth walls has been evaluated and analyzed. Throughout the article, the effect of different parameters such as angle of internal friction, soil unit weight, cohesion, using different materials in layers with 1.5m thickness and reinforcing elements' specifications has been analyzed. For detailed information from the site of the wall, a borehole was drilled to a depth of 30 meters and geotechnical tests were done in Hormozgan province (Iran). The results show that the lower length and tensile strength can be used with higher angle of internal friction and adhesion. Also, utilizing material in different layers produces a more favorable performance, optimization and decreases the strength of reinforcer elements.

Keywords: Geosynthetic Reinforced soil walls, Finite element, Deformation, Stability.

Son yýllarda, Takviye Edilmiþ toprak yapýlar, uygun performans, tasarým çeþitleri ve inþaat yöntemleri nedeniyle inþaat ve inþaat mühendisliði projelerinde daha cazip hale gelmiþtir. Bu yazýda sýrt sýrta takviyeli toprak duvarlarýn performansý deðerlendirilmiþ ve incelenmiþtir. Bu baðlamda, iç sürtünme açýsý, zeminin birim hacim, adezyon gibi farklý parametrelerin 1.5 m kalýnlýktaki tabakalardaki farklý zemin malzemelerinin kullanýmý ve takviye edici özellikleri gibi tanýmlamalar deðerlendirildi. Duvarýn temelinin geoteknik özelliklerinden ayrýntýlý bilgi için, 30 metre derinliðine varan bir sondaj yapýlmýþ ve iranýn Hormozgan ilinde geoteknik testler yapýlmýþtýr. Sonuçlar daha az uzunluk ve Çekme mukavemeti daha yüksek iç sürtünme açýsý ve Adezyon ile birlikte kullanýlabileceðini göstermektedir. Ayrýca, farklý katmanlarda malzeme kullanma daha uygun bir performans üretir, optimizasyon ve azalýr mukavemeti Takviye elemanlarýn.

Anahtar Kelimeler: Güçlendirilmiþ Jeosentetik toprak duvarlar, sýnýrlý eleman, þekil deðiþtirme, duraylýlýk.
