In this paper, a rheological model for rockfill is proposed and a method for solving is suggested. Based on the 3-dimensional finite element methods, the model is applied to analyse the influence of the rheology of rockfill to the Shuibuya concrete face rockfill dam. The calculation result indicates that the rheology of rockfill has effects on the dam, especially on the concrete face slab. Some characteristics of the influence caused by the rheology of rockfill to the SHUIBUYA CFRD are expatiated. It is necessary to consider the rheology of rockfill material in large dam design in various stages including construction and reservoir impounding period.
