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.
