摘要：

The seismic behavior of the concrete slab in concrete-faced rockfill dams (CFRD) is investigated, considering concrete slab-cushion layer interface effect. The interface is simulated by an advanced constitutive model capable of simulating the complex behavior of soil-structure interfaces such as particle breakage, stress-dilatancy, stress-hardening, cyclic accumulative contraction, and stress degradation. Stage construction and reservoir impoundment of the dam are simulated and the dam is subjected to two earthquake records. The concrete slab responses under static and dynamic conditions are examined, and the effects of reservoir water level, interface roughness, and the interface modeling approach on the concrete slab response are investigated.
