Abstract:
      Combing hydrodynamic pressure model and penalty function coupling algorithm,a numerical model and its solution approach were proposed for analyzing the seismic response of reservoir-dam-foundation system,considering the contact between dam and foundation as well as the boundary effect.The validity of the model is verified by comparing the numerical results with the experimental results and analytical solutions in the literature.It shows that the proposed model and approach is able to describe the seismic load acting on the reservoir-dam-foundation system and the dynamic response of the coupling system accurately with higher efficiency due to the application of penalty function to deal with fluid-structure interfaces.Application of the proposed model to analysis of a gravity dam demonstrates the applicability of the model to dynamic analysis of a reservoir-dam-foundation system,and the effect of foundation deformation on the dynamic response of the system has been analyzed further.
