Abstract
In this paper, a time domain dynamic analysis of the dam-reservoir- foundation interaction problem is developed by coupling the dual reciprocity boundary element method (DRBEM) for the infinite reservoir and foundation domain and the finite element method for the finite dam domain. An efficient coupling procedure is formulated by using the substructuring method. Sharan's boundary condition at the far end of the infinite fluid domain is implemented. To verify the proposed scheme, numerical examples are carried out and compared with available exact solutions and finite-finite element coupling results for the problem of the dam-reservoir interaction. Finally, a complete dam-reservoir-foundation interaction problem is solved and its solution is compared with previously published results.
