Based on a new kind of rockfill power function creep constitutive model which can simulate high confining pressure state of rockfill

the stress and deformation simulation analysis with consideration of rockfill creep are performed for Shuibuya concrete face rockfill dam (CFRD). The computation results show that the deformation of dam shows evident increment and stress of dam relax a little. The creep of the rockfill result to some increase of the normal direction deformation and stress of the concrete face. The reasonable creep model is adopted to simulate deformation of rockfill correctly

the results of which can offer some references for the construction process and the decision of the constructing time. It has also very important significance for that the stress and deformation of CFRD can be forecasted according to simulation analysis results.
