Sonlu Elemanlar Metodu Kullanarak Farklı Yol Üstyapı Tiplerinin Oturmaya Etkisinin İncelenmesi

Bu çalışmada, farklı yol tiplerinin oturma davranışı üzerine etkisi sonlu elemanlar yöntemi kullanılarak incelenmiştir. Analizlerde aynı temel ve alt temel tabakaları üstüne inşa edilen farklı yol kaplama cinsleri için analiz modelleri oluşturulmuştur. Maksimum büyüklükleri aynı değerde olan statik ve dinamik yüklerde oluşabilecek oturma değerleri için iki boyutlu hesaplamalar yapılmıştır. Farklı tekerlek aralıkları (15, 30, 60 ve 120cm) için statik ve dinamik yükler altında oluşan asfalt ve beton yol tiplerindeki oturma davranışları incelenmiştir. İlk olarak asfalt yol kaplamasında analizler yürütülmüştür. Daha sonra ise beton yol ve yarısı beton yol olup kaplamanın diğer üst yarısının asfalt kaplama olma durumları için analiz sonuçları karşılaştırılmış ve farklılıklar yorumlanmıştır. Böylece tekerlek aralığı, yükleme tipi ve kaplama cinslerinin kara yolunda meydana getirebileceği oturma davranışları nümerik bir çalışma ile değerlendirilmiştir.

Investigation of The Effect of Different Pavement Types on the Settlement Using Finite Element Method

In this study, the effect of different road types on sitting behavior was investigated by using finite element method. Analysis models were created for different types of road pavements built on the same base and subbase layers. Two-dimensional calculations were made for the settlement values that can occur in static and dynamic loads with the same maximum values. Settlement behavior of asphalt and concrete road types under static and dynamic loads for different wheel distances (15, 30, 60 and 120cm) were investigated. First, analyzes were carried out on asphalt pavement. Then, the results of the analysis were compared and the differences were interpreted for the case of the asphalt pavement of the other half of the pavement. Thus, both the wheel spacing, the type of loading and the type of pavement that can occur in the road behavior of the sitting behavior was evaluated with a numerical study.
