چکیده مقاله
This paper details the influence of material properties change of discontinuous rock foundation on the seismic behavior of arch dams In this regard, proper modeling of far boundary conditions at far end of rock foundation and reservoir fluid domain is important Nonlinear seismic response of dam reservoir foundation system includes dam canyon interaction, dam body contraction joint opening, discontinuities sliding planes of foundation rock and failure of the jointed rock and concrete materials Therefore, a finite element program for nonlinear dynamic analysis of 3D dam reservoir foundation system was developed Karun 4 Dam as a case study was analyzed the results revealed the essential role of modeling discontinuities and boundary conditions of rock foundation under seismic excitation
