ISSMGE Outstanding Geotechnical Project Award goes to “Busan-Geoje Fixed Link Immersed Tunnel”. Mr Keunyoung Kim, Managing Director of Daewoo Engineering & Construction Co. Ltd was responsible for this huge project with connection to the Korean Geotechnical Society, chaired by Professor Yeon-Soo Jang. This impressive immersed tunnel, 3.3 km long, is part of a very large project connecting the city of Busan to the Island of Geoje. The soil was 20 m of very soft marine clay which had to be improved by different methods to minimize the differential settlement. The tunnel was completed in 2010.
