Abstract：Transient seepage analyses for Gouhou concrete faced rockfill dam were conducted using the unsaturated soil seepage theory.Through comparison of the seepage fields in a uniform dam and an evidently stratified dam,the evolution of seepage with time and the distribution characteristics of the hydraulic parameters in the two cases were studied.The effects of the stratification of rockfill on the seepage field and the stability of the dam slope were highlighted.
