Geosentetik Donatı Sayısı ve Konumunun Farklı Boyutlu Yol Numuneleri Üzerine Etkisinin İncelenmesi

Bu çalışmada, sonlu elemanlar yöntemi kullanılarak oluşturulan modeller için geosentetik donatının etkileri incelenmiştir. Plaxis 2D programı ile farklı model boyutlarında seçilen örnekler üzerinde yapılan analiz sonuçları değerlendirilmiştir. 5 cm ile 960 cm arasında alınan farklı model genişlikleri için yol temel tabakası modellenerek gerilme deformasyon davranışı ve oturma miktarları değerlendirilmiştir. Modellerin kırılma davranışları ile modeller içine konulan tek ve çoklu donatı tabakası (1, 2 ve 3) kullanılma durumları için de değerlendirmeler yapılmıştır. Tek donatının numune içinde farklı bölgelere konulmasının etkileri de karşılaştırılmıştır. En iyi performansın üç adet donatı kullanılması durumunda görüldüğü belirtilebilmektedir. Donatısız durumda model boyutu pek etkili olmasa da donatılı modeller için numune ölçüleri etkili olabilmiştir. Ayrıca, oturma ve modellerin kırılma modellerinde donatının etkili olduğu görülmüştür.
