Abstract

Son
yıllarda, Takviye Edilmiş toprak yapılar, uygun performans, tasarım çeşitleri
ve inşaat yöntemleri nedeniyle inşaat ve inşaat mühendisliği projelerinde daha
cazip hale gelmiştir. Bu yazıda sırt sırta takviyeli toprak duvarların
performansı değerlendirilmiş ve incelenmiştir. Bu bağlamda, iç sürtünme açısı,
zeminin birim hacim, adezyon gibi farklı parametrelerin 1.5 m kalınlıktaki
tabakalardaki farklı zemin malzemelerinin kullanımı ve takviye edici özellikleri
gibi tanımlamalar değerlendirilmiştir. Duvarın temelinin geoteknik
özelliklerinden ayrıntılı bilgi için, 30 m derinliğine varan bir sondaj
yapılmış ve iranın Hormozgan ilinde geoteknik testler yapılmıştır. Sonuçlar
daha az uzunluk ve Çekme mukavemeti daha yüksek iç sürtünme açısı ve Adezyon
ile birlikte kullanılabileceğini göstermektedir. Ayrıca, farklı katmanlarda
malzeme kullanma daha uygun bir performans üretir, takviye elemanlarının
optimizasyon ve mukavemeti azalır.

Parametric analysis of back-to-back reinforced earth retaining walls

Abstract

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 1.5 m 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 m 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.
