creeping of the dam body can be critical. In this paper
a numerical procedure is developed to study the influence of the creep deformation on the separation between concrete slab and cushion layer in high CFRD. The procedure is based on the finite element method and the direct constraints method is used to simulate the contact behavior between the concrete slab and the cushion layer. The procedure is applied to Tianshengqiao-I CFRD. Based on a comparison of the numerical results with in-situ measurements
the effects of creep deformation on the separation between concrete slab and cushion layer are investigated.
