Given the advantages of simple structure, construct economical and low influenced by weather conditions, more and more engineers are turning their attention to the rockfill dam with asphalt concrete core. In this paper, the author uses the nonlinear Duncan-Chang E-B model to simulate the constitutive law of rockfill body and asphalt concrete core, considers the contact behaviors between rockfill body and asphalt concrete core and the wetting deformation of upstream rockfill body, then analysis the rockfill dam and asphalt concrete core by three dimension FEM, the result shows: considering the wetting deformation of upstream rockfill body is closer to the reality, the stress level of the dam is less than 1.0, vertical stress in asphalt concrete core on arbitrary elevation is greater than water pressure on the same elevation, and the static lateral pressure coefficient are all less than 0.5, so the design of the rockfill dam with asphalt concrete core is reasonable.
