Gömülü HDPE Borularda Esneme Davranışının İncelenmesi

Abstract

Bu çalışmada esnek boruların tasarımı ve performans limitlerini etkileyen faktörlerden boru çember rijitliği, gerilme, dolgu yerleşim relatif kompaksiyonu ve dolgu malzeme türünün boru-zemin etkileşimi üzerindeki etkileri incelenmiştir. Bu kapsamda kalın dolgular altında gömülü bulunan esnek boru davranışının incelenmesi amacı ile yapılan proje kapsamındaki arazi deneyleri kullanılmıştır. Boru özellikleri, dolgu yerleşimi, dolgu malzeme türü dikkate alınarak söz konusu borularda meydana gelen esnemeler, Geliştirilmiş Iowa yaklaşımları ve sayısal analizler ile incelenmiş ve elde edilen sonuçların arazi ölçümleri ile karşılaştırılması yapılmıştır. Yarı amprik yaklaşımlar ve sayısal analizlerden hesaplanan esnemelerin arazi ölçümleri ile yaklaşık olarak uyumlu olduğu belirlenerek çember rijitliği düşük ve yüksek olan yüksek yoğunluklu polietilen boruların tasarımı için bu amprik yaklaşımların ve iki boyutlu sayısal analizlerin kullanılabileceği görülmüştür.
