Abstract: The aseismic performance of shallow buried water-conveyance tunnel in soft soil area is becoming more and more important with the development of large-scale water conveyance projects. In the big diameter water-conveyance tunnel, on account of large mass and sloshing of inner water under the vibration, which will bring water－tunnel lining interaction. All the above will affect dynamic response of tunnel lining. Aiming at this problem, the paper studies water-conveyance tunnel by dynamic fluid-structure coupling method. Especially, inner water is modeled by potential-based liquid element. The numerical results show that the inner water has great effects on the frequencies and dynamic response of water-conveyance tunnels.

Key words: water-conveyance tunnel, fluid-structure interaction, earthquake, potential flow, dynamic response
