Abstract:
In this paper, time domain dynamic analysis of dam-reservoir interaction is presented using finite difference method. A semi-implicit scheme is used for the discretization of the governing equation of dam, and an explicit scheme is used for the discretization of the governing equation of fluid. Water is considered compressible but its internal viscosity is neglected. A Sommerfeld’s radiation condition at the infinity boundary of the fluid domain is implemented. To verify the proposed method, numerical examples are given to be compared with the existing solutions. The result shows a good agreement with semi-analytical solution. Finally, the effects of reservoir bottom absorption, the free surface waves of the reservoir and the vertical component of earthquake are analyzed and the results are presented.
