| Abstract: | The overview of a concrete faced rockfill dam（CFRD） project and rheological models of rockfill were presented brief- ly. The 3--D finite element method was used to simulate and calculate damming and the impounding process of the CFRD. By contrasting the result from taking into account the rheological effect with that from without taking account of rheologieal effect of roekfills, the influence of rheological behavior of rockfill on deformation and stress of dam and face slab were analyzed and studied. |
