Baret Kazıklı Radye Temellerin Üç Boyutlu Sonlu Elemanlar Analizi

Yüksek katlı yapı temellerinde kullanılan baret kazıklı radye sistemlerinin oturma analizlerinin yapılması, geoteknik mühendisliği açısından yeni bir bilimsel mücadele alanı olmuştur. Bu temel sistemlerinin sayısal üç boyutlu modellerinin görüntü işleme tekniğiyle daha gerçekçi olarak yapılabildiğini göstermek amacıyla, Viyana'daki Avrupa’nın en uzun gökdelenlerinden biri olan DC kulelerinin temel sistemleri ayrıntılı bir şekilde modellenmiş ve kulelerin birbirlerine etkisi incelenmiştir. Bu araştırma kapsamında geliştirilen üç boyutlu sonlu elemanlar (3B SE) modelleri sayesinde, geoteknik mühendisliğinde önemli bir temel çeşidi olan baret kazıklı radyelerin oturma analizleri, komşu kazık sistemiyle birlikte analiz edilerek ölçüm sonuçlarıyla kıyaslanmıştır. Bu bildiride sunulan analizler sayesinde, literatürde daha önce sunulan 3B SE analizi geliştirilerek oturma analizlerinin daha hassas olarak ileri bir modelleme tekniği ile yapılabileceği açıklanmıştır.

Anahtar Kelimeler:

Baret kazıklı radye, Görüntü işleme, Sonlu elemanlar analizi, Üç boyutlu modelleme, Oturma analizi
