Özet:

 In Turkey and in the world, freight-passenger transportation is mostly provided by road transportation, and flexible and rigid superstructures are widely used as the superstructure type. Good design of the superstructure ensures that it can remain intact under the traffic load for many years. Stress and displacements play a major role in the design of pavement layers such as pavement, foundation and sub-base. The complexity of the pavement design has led researchers to computer-aided software, so that complex problems can be easily simulated and solved. In this study, rigid and flexible pavements with different pavement layer thicknesses 90 mm, 120 mm and 150 mm were modeled in the ANSYS program using the finite element method and their displacement and stress distributions under traffic loads were investigated. According to the stress distribution results, the stress values of flexible pavements were lower than the stress values of rigid pavements. The displacement in flexible pavements was more than the displacement in rigid pavements.

 Türkiyede ve dünyada yük- yolcu taşımacılığı çoğunlukla karayolu ulaşımı ile sağlanmakta olup üstyapı tipi olarak esnek ve rijit üstyapılar yaygın olarak kullanılmaktadır. Üstyapının iyi tasarlanması uzun yıllar trafik yükü altında bozulmadan kalabilmesini sağlamaktadır. Kaplama, temel ve alt temel gibi üstyapı tabakalarının tasarımında gerilmeler ve yer değiştirmeler büyük rol oynamaktadır. Üstyapı tasarımının karmaşıklığı araştırmacıları bilgisayar destekli yazılımlara yöneltmiş ve bu sayede karmaşık problemler kolaylıkla simüle edilebilir ve çözülebilir olmuştur. Bu çalışmada, farklı kaplama tabakası kalınlıklarına 90 mm, 120 mm ve 150 mm sahip rijit ve esnek üstyapılar sonlu elemanlar metodu kullanılarak ANSYS programında modellenmiş ve trafik yükleri altındaki yer değiştirme ve gerilme dağılımları incelenmiştir. Gerilme dağılımı sonuçlarına göre, esnek üstyapıların gerilim değerleri, rijit üstyapıların gerilim değerlerinden daha düşük çıkmıştır. Esnek kaplamalardaki yer değiştirme ise, rijit kaplamalardaki yer değiştirmeden daha fazla elde edilmiştir.
