%X Based on a rockfill power function rheology constitutive modelt,he stress and deformation analysis with the consideration of rockfill rheology are performed for Shuibuya concrete face rockfill dam(CFRD).The computational results show that the deformation of dam shows evident increment and the rheology has an obvious influence on the deformation and stress of the face.Due to influence of rockfill rheology,the shortest time interval exists between construction periods of concrete faces lying on the rockfill and the rockfill.At the same time,the minimum elevation difference should also be satisfied between construction elevation of concrete faces lying on the rockfill and the rockfill top,in order to avoid inconsistent deformation between concrete faces and the rockfill.So it is very important that construction processes of rockfill and concrete face must be optimized and deformation of face should be reduced as possible.
