The model presented in the companion paper is validated in both the linear and nonlinear cases under steady-state single frequency harmonic and transient ground motions. The crest acceleration responses of the Santa Felicia earth dam subjected to the 1971 San Fernando earthquake and of the Long Valley earth dam subjected to the strongest of the 1980 Mammoth Lake earthquakes are computed and compared with the motions recorded at the site. Acceleration time histories for the solid and fluid phases in both horizontal and vertical directions, as well as stress-strain and pore water pressure-strain time histories for points along the height of the dam are presented. The ability of the model to simulate the occurrence of liquefaction in a dam is also demonstrated.
