ABSTRACT PRELIMINARY DESIGN AND ANALYSIS FOR AN IMMERSED TUBE TUNNEL ACROSS THE İZMİR BAY In this study, a preliminary design and analysis of an immersed tube tunnel is presented. The tube tunnel will connect the two coasts of the İzmir Bay and whereby will ease the transportation of the city. The reason to suggest an immersed tube tunnel is due to the shallow water depth (
ÖZET İZMİR KÖRFEZİ İÇİN BATIRMA TÜP TÜNELİN ÖN TASARIMI VE ANALİZİ Bu çalışmada, İzmir Körfezi’nin iki yakası arasında ulaşımı rahatlatmak için önerilen batırma tünelin ön tasarımı ve analizi yapılmıştır. Batırma tünelin seçilmesinin nedenleri; İzmir Körfezi’nin oldukça sığ su derinliğine(
