Seismic Analysis of Submerged Tunnels

The paper first presents alternative possibilities for underwater tunnel benefits for crossing deeply and widely water barieras. After that the 2D numerical model for the seismic analysis of underwater structures, which simulates dynamic interaction between structure and water in seismic conditions, is briefly presented. The main nonlinear effects of water-structure system are modeled. The analysed example of underwater tunnel over Hø ; ; gsfjord in Norway ilustrates some possibilities of the presented numerical model and the developed software.
