Abstract: Based on previous researchers, this paper establishes a rheology model of rockfill used in the rheology analysis of concrete face rockfill dam despiting the rockfill microstructure. In this model, the instantaneous elasto-plastic deformations of rock fills are computed by the oblong-parabola two yield surface model, and considering the time effects, the time dependent visco-plastic deformations are derived from the empirical equation of hyperbolic function .The reliability of this rheology model is proved to be good after perfo rming inverse problems with deformation records in-situ .

Key words: concrete face rockfill dam , rockfill ;rheology model
