Based on the prototype monitoring data of Yele asphalt concrete core rockfill dam and 3-D finite element calculation results, the gray aging model of GM(1, 1, t) was applied to displacement hybrid-model of high earth-rock dam and used for Yele rockfill dam. The results showed that the displacement hybrid model has a high precision and an effective prediction, which can meet the engineering

Moreover, the model factor has a definite physics meaning, and the convergence and divergence of aging displacement components may be judged easily, and the dam can be monitored highly contrapuntally. The model has some reference value for model research of same dam.
