Abstract
Alüvyonlu
akarsu tabanına inşa edilen köprülerde, köprü ayaklarının emniyetli tasarımı
için ayaklar etrafında oluşan maksimum oyulma derinliğinin pik tasarım debisine
erişme süresine kadarki zamansal gelişimini incelemek gerekmektedir. Bu
çalışmada, akım doğrultusuna paralel arka arkaya konumlanmış ikili köprü
ayakları etrafında, temiz su ve üniform taban malzemesi koşullarında oluşan
oyulma çukurunun yüzey özelliklerini incelemek amacıyla deneysel bir araştırma
yürütülmüştür. Deneyler, değişik ayak çapı ve ayaklar arası mesafelerde ikili
özdeş silindir ayaklar kullanılarak değişik akım şiddetleri ile
gerçekleştirilmiştir. Çalışmanın sonucunda, maksimum temiz su oyulmasının
zamansal değişimini tahmin eden bir denklem üretilmiştir. Deneylerin test
aralığında, önerilen denklemin deneysel bulgularla uyum gösterdiği
gözlenmiştir.
