In this paper, the results of a numerical analysis to obtain the stress intensity factor in mixed mode, KI and KII, in a cracked concrete dam submitted to seismic loads are presented. The numerical model was implemented in the commercial finite element code Abaqus/Standard. It was used Koyna dam geometry but it was included a crack parallel to the horizontal plane. In order to evaluate the importance of guarantee an adequate crack sealing using epoxy resin, a second parametric study was done considering partial crack sealing. The study results allow determining the cracks that endangered the dam structural integrity under seismic loads.
