  • The stratified ocean internal wave flow field was established based on the potential flow function theory. The joint force by internal wave and sea current was considered with the Morison method to establish a nonlinear vibration mathematical-physical model of tunnel-fluid interaction. The corresponding vibration differential equations were solved numerically with the Galerkin method to study the multimodal dynamic response behaviors of the submerged floating tunnel under combined internal wave and sea current effect. According to the calculation and analysis of a practical example on the proposed tunnel, the first order mode contributed most of the displacement response.The effect of internal wave on the the joint force by internal wave and sea current could not be ignored, it resulted in a substantial increase of the response amplitudes of the first and third order modes and made the responses strongly nonlinear. The research results provide helpful discussions for the structural load analysis of submerged floating tunnels and for the study on environmental loads upon ocean engineering structures in a complex environment.
