Seismic Response of Submerged Floating Tunnel Based on Numerical Analysis
To study the seismic response of submerged floating tunnel, a numerical model of submerged floating tunnel is set up based on the potential fluid theory. According to the parameters of designed submerged floating tunnels at home and abroad, main factors that affect the dynamic response of submerged floating tunnel were analyzed by numerical method. The results show that, the investigated parameters, such as tether spacing, external diameter of tube, immersion depth of tube, water depth and tube concrete thickness, have strong influence on the global behavior of the submerged floating tunnel. Definitely, by the caring choice of such features, it is possible to optimize the submerged floating tunnel structural behavior.
