The Deep Soil Mixing for the Galataport Project in Istanbul, Turkey
Article Type: Case Study

Chiarabelli, M.


The paper describes the adopted technologies and performance controls related to a special geotechnical engineering solution provided within the scope of the Galataport Project, in Istanbul, Turkey. The scheme is the one applied to the new quay of Sal?pazar?, 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 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. A cross section of the executed treatment could be inspected on site during excavation, which shows the effectiveness of the executed works. The results of the in-situ and laboratory tests carried out on the improved soil during the preliminary field trial test and after the completion of works are also presented.
