| Abstract: |
A special feature of the Busan-Geoje Fixed Link in South Korea is the foundation of an immersed tube tunnel in a trench of soft marine clay. The tunnel is subject to wave loads due to 9.2 meter high hurricane waves which jeopardize the stability of the tunnel. Analytical analyses, scale model tests and numerical analyses have been made to investigate this problem. This paper gives an overview of the analyses, performed from schematization of the non-linear waves to pressure variations at seabed, modelling of the wave induced groundwater flow and its effects on the tunnel buried in the seabed. This is followed by a discussion of the results and consequences for the design of the tunnel. |
