The finite element stress analysis is made on a concrete gravity dam with the structure analysis software based on ANSYS ; in which the effect of the ratio of the upstream slope on the normal stress of the dam heel is studied for both the completed condition and operation condition of the dam with or without arrangement of anti-seepage curtain and drainage system, and then some valuable conclusions are obtained; which can be provided as the references for the designer concerned.
