An new type of traffic structure crossing straits and lakes-Submerged Floating Tunnel has received much attention all over the world increasely.Based on the displacement potentials

and taking submarine rock and soil as elastic half-space and seawater as ideal fluid

anchors as rigid restraints

the theoretical formula of the hydrodynamic pressure on rigid submerged floating tunnels with rigid anchor restraints are derived with plane SV-wave incident from submarine rock and soil.Subsequently

the effects of different submarine rock and soil parameters

and different frequencies and directions of plane SV-wave on the hydrodynamic pressure on submerged floating tunnels are analyzed.It could be concluded that all the parameters have significant effects on the hydrodynamic pressure on Submerged Floating Tunnel except the submarine and soil density.
