Submerged floating tunnels have been proposed for many strait crossing project, but seismic response of the tunnels have not been investigated in detail. This paper presents analytical method to estimate response of submerged floating tunnels to vertical seismic excitations. Based on the one-dimensional wave propagation method, response of seabed and sea water to the input earthquake motions is calculated: Also hydrodynamic force of the tunnel is numerically evaluated by the boundary integral method using the Green's function. Then the equation of motion for the tunnel is established and response of the tunnel acceleration and the tendon forces is calculated by solving the equation. ƒL[ƒ[ƒhi‰pjF submerged floating runnels, earthquake, numerical analysis ‹LŽ–‹æ•ªF - ‹æ•ª @@@ˆÏˆõ‰ï˜_•¶W
