Galata Port Project in Istanbul: Rehabilitation and Restoration Works of the Terminal for Cruise Ship and Historical Surrounding Area

摘要

The paper describes the design principles, adopted technologies, and performance controls related to two main geotechnical engineering solutions provided within the scope of the Galataport project, in Istanbul, Turkey. The first scheme is the one applied to the new quay of Salipazan, which is a combination of retaining structure and ground improvement, formed by a combi-wall, a reinforced concrete diaphragm wall and a soil improvement by deep soil mixing (Turbojet). The second is an innovative solution employed for the deep basement excavation in Karakoy, formed by a combination of seepage control, ground improvement, and load bearing elements, executed with double-fluid jet grouting, pseudo-elliptical jet grouting, and permanent micropiles, respectively. The paper highlights the importance of employing cutting-edge technologies within the foundation engineering field and state-of-the-art electronic control devices, in parallel with the essential human expertise, in order to obtain the desired results in this high profile project.
