| Abstract: |
The immersed tunnel part of the Busan-Geoje Fixed Link is the deepest and 2nd longest segmental concrete immersed tunnel at the time of opening the link for traffic in December 2010. With more than 140 articulation joints along the immersed tunnel, design of the joints is a key element of the structural design. This paper describes some of the main challenges for the structural design of the immersed tunnel especially the watertightness design of the joints and design of the shear keys and some of the Soil Structure Interaction (SSI) analysis required to determine shear forces and movements of the joints. |
