Based on a new kind of rockfill power function creep constitutive model which can simulate high confining pressure state of rockfill
the developing rule of rockfill creep and the engineering method of control creep are studied. The results show that the computation value of dam deformation will be less than the real one without consideration of rockfill creep because of arch action. The creep of the rockfill during early stage is suppressed. But the arch action will be weakened with heightening of dam
increasing of water pressure and developing of rockfill creep. The temporary section of CFRD is made use of blocking water or overflowing as possible in order to decrease rockfill creep during late stage. The construction date of the face slab delays several months than the rockfill below the face slab
