Öz

Bu çalışmada esas olarak
taş kolon ve düşey dren yöntemlerinin konsolidasyon oturmalarının azaltılması
ve konsolidasyonun hızlandırılması açısından performansları değerlendirilmiştir.
Çalışmanın ilk aşamasında taş kolonlar ve düşey drenlerinin kullanımı ve bu
yöntemler için geliştirilmiş sayısal analiz yöntemleri araştırılmıştır.
Çalışmanın sonraki aşamasında, düşey drenlerin tasarımı için önem arz eden bazı
tasarım parametrelerinin etkisi Plaxis yazılımı kullanılarak sayısal olarak
araştırılmıştır. Son olarak, Changi Doğu Islah Projesi analiz edilmiştir.
Analizler iki pilot araştırma için yapılmış olup, analizlerde taş kolon ve
düşey drenlerin konsolidasyon davranışı modellenmiştir. Sayısal analiz
sonuçları, arazi ölçümlerine bakılarak değerlendirilmiş ve bu iki iyileştirme
yönteminin konsolidasyon davranışı karşılaştırılmıştır. Karşılaştırma
analizleri sonucunda, taş kolonların özellikle konsolidasyon oturmalarının
azaltılması ve konsolidasyonun hızlandırılması açısından daha fazla avantaj
sağladığı tespit edilmiştir.

Anahtar Kelimeler
