Abstract

We hereby presents an analytical method to estimate response of submerged floating tunnels to vertical seismic excitations. Based on the one-dimensional duplicate reflection theory, the response of the sea bottom and water to the input earthquake motion is calculated. Also hydrodynamic force on the tunnel is numerically evaluated by using a velocity potential theory. Then an equation of motion of the tunnel is established, and the response of tunnel acceleration and cable tension is calculated for a prototype tunnel.
